I've just started tinkering with conky, and I'm hoping the StackOverflow crowd can share some of the cool things they've done with this tool.
Scripts and .conkyrc files specifically geared towards developers would be especially good to see. Some good examples of developer-centric functions would be repository-monitors or heck, even something that monitors StackOverflow.
Screenshots of what the functionality actually looks like would be appreciated as well.
I have an old AT modem that understands caller ID connected to my computer, so it keeps a log of incoming calls, and will match them to numbers in my address book. I have conky set to show the last few entries from the log.
(An incoming call also triggers a script that displays the call details on the screen using osd_cat, and pause the music player too.)
Other than that, just the usual weather forecast and system info summary.
This link just came up on reddit today, has some very well-done conky layouts: http://www.linuxhaxor.net/2009/05/07/8-beautiful-conky-desktop-monitor-setup/
I've just written a bash/shell script that uses grep to get today's TV shows from a txt file. Here's the format of the txt file:
Monday:
Family Guy (2nd May)
Tuesday:
House
The Big Bang Theory (3rd May)
Wednesday:
The Bill
NCIS
NCIS LA (27th April)
Thursday:
South Park
Friday:
FlashForward
Saturday:
Sunday:
HIGNFY
Underbelly
Here is the shell script which was saved in ~/bin and made executable:
#!/bin/bash
MYDATE=$(date +%A)
grep -A10000 $MYDATE /path/to/to_watch/list.txt | grep -B10000 -m1 ^$
And here is the line to add to your .conkyrc file (below 'TEXT')
$color${execi 3600 tv_today}
I think the regex/grep stuff needs some work (it doesn't like crlf line breaks) but it works.
Hope this gives someone some ideas of cool stuff to do with Conky...
Edit 2010-05-02:
Thanks to user tiftik for this more elegant awk/regex replacement for the bash script:
#!/bin/bash
awk '/^'`date +%A`':$/,/^$/ {if ($0~/[^:]$/) print $0}' /path/to/to_watch/list.txt

I need some sort of schedule thing to schedule a task to happen at x:y (12:00 for example) in Tcl.
The scenario is a router using Openwrt with Tcl 8.6.10 with limited RAM and storage where I have some sort of IRC client "bot" (using socket to connect). The "bot" was just a barebone that I modify to suit my needs. Most of the things work fine, except that I don't have way to schedule easily things. I wanted something like how eggdrop has "bind time" where the bind thing is "bind time flag "cron-style string" caller".
The "bot" scheme is like:
Main Tcl script:
<info+code to connect to IRC>
<while loop>
<some code in case of IRC disconnection>
<list of files with tcl code aka sub-scripts>
<usage of source based from a list of the filenames>
<code for error handling>
<end of while loop>
The list of files is source filelist.tcl, where filelist.tcl is a set var {filename1.tcl filename2.tcl...}. The filenamex.tcl has some basic code to respond to IRC server or IRC input from channels and reply to channels.
I can make some sort of schedule if I base a execution like if {[clock format [clock seconds] -format "%H:%M"]=="12:00"} {code to execute} and hopefully wait for a server ping/pong but that can lead to repeated code inside of the if body.
I been looking around and found a package called cron but I don't know how to use it correctly because there are not many examples and I don't know to use vwait properly and I don't want vwait to hang the bot waiting for a value to change. I also read about tcl threads for maybe parallel execution.
So I need some code inside of a sub-script that looks like (a package cron style):
#beginning of file
#add a task specifying hour and minute
task-at "12:00" proccaller
proc procname {optional} {
<some code to be executed at specific hour+time>
}
#end of file
I also don't know how to use after command to use it.
How can I accomplish I want?
Thanks for the replies and yes, it would help if I study event loops and coroutine, which probably comes next.
Some time has passed since I posted the question and kinda sorted the thing by creating a sub-script in a folder named scripts with the following structure:
#beginning of the script
if {![file exists executed]} {set executed "no"}
#the following clock instruction returns for example: Tuesday 22:14
switch -glob -- [clock format [clock seconds] -format "%A %H:%M"] {
"*12:00" - "*12:01" {
#Basic example of sending a message to the irc channel when it's midday
if {$executed=="no"} {
puts $fd "PRIVMSG #CODE :It's midday right now."
flush $fd
set executed "yes"
}
}
#...more time comparisions and code
default {set executed "no"}
}
#end of script
And the script is almost the top of the list of scripts to be loaded so if I wish to send some command down stream at giving time, the command can be executed.
There is double timings because the "bot" reacts, at least at minimum, to the irc server's ping which happens each 90 seconds and it may skip some minutes.
This is not an answer but an unproper workaround.
I am attempting to send a file from IFS to an outq on our AS/400 system. Whenever I do, I get exactly what I send, as well as a line of "#" symbols of varying lengths appended to the end.
Here's the command I'm using:
qsh cmd('cat -c /path/test.txt | Rfile -wbQ -c "ovrprtf file(qprint)
outq(*LIBL/ABCD) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)"
qprint')
The contents of test.txt is just Hello World!
The output I get when I send the command is
Hello World!####################################################################
I have not found any posts online about a similar problem, and have tried changing values and looking for additional switches to get it to work. Nothing I'm doing seems to fix the issue.
Is there a command or switch that I am missing, or is something I have in there already causing this?
EDIT:
I found this documentation which is the first time I've seen this issue mentioned, but it's not very helpful:
“Messages for a Take Action command might consist of a long string of "at" symbols (#) in a pop-up message. (The Reflex automation Take Action command, which is configured in situations, does not have this problem.) A resolution for this problem is under construction. This problem might be resolved by the time of the product release. If you see this problem, contact IBM Software Support.”
The only differences are: 1) this is not a pop-up message, it's printed. 2) I don't believe we use Tivoli Monitoring, although I could be wrong.
Assuming we do use Tivoli Monitoring, what would the solution be? There's no additional documentation past that, and I am not a system administrator, so I can't really make the call to IBM Software Support myself. And assuming we DON'T use it, what else could cause this issue?
I get different results, yet similar. I created a test.txt with Windows Explorer, put in Hello, world!, saved it and tried the script. I got gibberish for the 'Hello, world!' and then the line of # symbols.
My system is 7.3 TR5, CCSID 37 (US English) and my IFS file is CCSID 1252 (Windows English). Results did not change if I used a stream file of CCSID 819 (US ASCII).
I didn't have any luck modifying Rfile switches.
I found that removing devtype(*userascii) produced printed output in plain English without the # symbols. Do you really need *USERASCII? I would think that would be more for a pre-formatted 'print-ready' file like Postscript or the like.
EDIT: some more things to try
I don't understand why *USERASCII is adding those # symbols; it looks like a translation issue.
I tried this and still got the extra ###... You might have to play with the TOCCSID() parameter. Although a failure, it did give me an idea: what if those # symbols are EBCDIC spaces being sent as-is to the *USERASCII print stream? All we'd need is a way to send only the number of bytes in the stream file, without any padding.
CRTPF FILE(QTEMP/PRTSTMF) RCDLEN(132)
CPY OBJ('/path/test.txt') TOOBJ('/qsys.lib/qtemp.lib/prtstmf.file/prtstmf.mbr') replace(*yes)
ovrprtf file(qprint) outq(*LIBL/prt3812) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)
cpyf prtstmf qprint
The data in QTEMP/PRTSTMF is in ASCII; DSPPFM shows that much. It also shows a bunch of spaces: after all, it is a fixed length file. My next step was to write an RPG program to read the stream file and print it, but Scott Klement already did that: http://www.scottklement.com/PrtStmf.zip
This works on my system:
ovrprtf file(qsysprt) outq(*LIBL/abcd) devtype(*USERASCII) rplunprt(*no) splfname(test) hold(*no)
prtstmf stmf('/path/test.txt') outq(abcd)
I would like to store the message of an alert in influxDB using influxDBOut. Is is possible?
Here is my tick script
batch
|query('SELECT mean(value) as value FROM "metrics"."autogen"."__MEASUREMENT__"')
.period(15m)
.every(5s)
.groupBy(*)
.fill(0)
|alert()
.id('[METRICS] - {{ .Name }}')
.message('{{ .ID }} changed state to {{ .Level}} [{{ .Time }}] => The metric {{ index .Fields "value" }} in the last 15m.')
.info(lambda: TRUE)
.warn(lambda: "value" < __WARN_THRESHOLD__)
.crit(lambda: "value" < __CRIT_THRESHOLD__)
.stateChangesOnly()
.levelField('Severity')
|influxDBOut()
.database('alerts')
.retentionPolicy('autogen')
.measurement('__MEASUREMENT__')
.tag('Condition', 'Low')
Thank you in advancek
Unfortunately there currently isn't a way to achieve a result like this. If this functionality is particularly important to you, I'd recommend opening up a feature request on Kapacitor detailing your use case.
Q:
I would like to store the message of an alert in influxDB using influxDBOut. Is is possible?
A:
Michael definitely knows waayyy better than I do. Yes, there is no straight forward way out at the moment. However it doesn't mean that this is not do-able.
What you're trying to do here is a typical software dev problem.
Open a file
Read its content
Format it
Write it somewhere else.
You can handle this sort of problem in any scripting language that supports the highlighted points above. The only tricky thing is probably #4 as not every scripting language has a influxdb database driver, but still you can do curl commands to perform the writes.
What you could do is
Modify your TICK script to output the alert to a file. See log() of alert node.
Write a simple script to lookout for any new files written by the log() functionality.
Parse the file
format the data so that they can be inserted into a measurement
setup a scheduler like unix's cron to periodically run your script.
Hope it helps.
I am extremely new to Informix and am having some trouble trying to get sqldemo installed.
Set up so far:
openSuse 12.1 (32 bit)
Informix Growth Edition 11.70 UC6
Informix SQL Developer 7.50 UC6
Informix RDS 7.50 UC6
Informix ID 7.50 UC6
After struggling a few days and a lot of reading of http://publib.boulder.ibm.com/infocenter/idshelp/v117/index.jsp, I managed to get Informix installed and On-line.
I also opted to install the demo database instance that comes with the installation.
I now and attempting to get started with Informix 4GL by Example.
I am trying to get the sqldemo database up. I don't know if it will replace the previous instance installed with Informix, but that is a different problem.
Right now as per the document, running the following should set up the DB:
sqldemo stores2t -log
I however get an error: "Invalid Locales set !!".
I have tried looking up this error and also in the documentation.
I have tried setting the CLIENT_LOCALE and DB_LOCALE in my .profile file.
For example:
export CLIENT_LOCALE=en_US.CP1252 and
export DB_LOCALE=en_US.819
This has not helped.
A push in the right direction, or perhaps some other documentation I could read that would explain things better would really be appreciated.
If any other information is required from me, please do not hesitate to ask.
Update 1
Thanks so much for the response.
A couple of things firstly that I have tried since your post.
Changed the the CLIENT_LOCALE and DB_LOCALE as you specified - Same error - So i removed it as you said it should not be set.
Fixed a problem in my PATH and made sure it has /usr/informix/bin - Same Error
INFORMIXDIR is /usr/informix
INFORMIXSERVER is ol_informix1170 (This is from the database that was installed with the informix install, don't know if this must be changed? and if so to what?)
Ran the script you mentioned, result :
INFORMIXDIR=/usr/informix
INFORMIXSERVER=ol_informix1170
INFORMIXSQLHOSTS=/usr/informix/etc/sqlhosts
LANG=en_US.UTF-8
ONCONFIG=onconfig
I noticed I had set the language to UK, which made the Locales en_gb instead if en_us, so tried changing that in my .profile, which did not help, so also tried changing the language to US and the locales to en_us, but this made no difference.
As for what you said about the sqldemo script and the already installed db, It is fine if that db is removed as this is just a test VB box for me to learn on.
Could the $INFORMIXSERVER set as ol_informix1170 be the problem?
Thank you once again for the help.
Neill
Update 2
Thanks again for the response.
A few things to note.
The dbenv results I posted is all that shows which i assume/presume (uh-oh) means that the other environment variables are not set. Which of the environment variables you posted are absolutely necessary for it to work?
As above, Where would I find the terminfo file, or does this need to be created?
As above, the SQLEXEC variable... where would I find sqlrm? I can somewhat remember from the documents I have read I think it should be $INFORMIXDIR/lib? but I only have an esql directory. Is this correct.
Barring that something in the first 3 above is not causing more problems, when trying your suggestion of DEMOPATH=en_us/0333 sqldemo stores2t -log I receive the following error:
Sorry, cannot read the mkstores3 program required to build the demonstration database. Check the /etc subdirectory of INFORMIXDIR (/usr/informix).
Checking /usr/informix/etc shows indeed that there is no mkstores3 file.
Attempting your further note of isqldemo, I get the following error:
/usr/informix/bin/isqldemo: line 58: /usr/informix/demo/sql/en_us/e01c/isqldemo: No such file or directory.
I guess this makes perfect sense as there is no e01c directory, just the 0333 directory.
Right now anything you can tell me would indeed be a consolation because my newb-ness to generally Linux and definately Informix is a big factor. Interesting that this bug has been around for so long. I guess way more experienced folk than I figured out how solve it on their own, or just never bothered with the sqldemo.
I guess that will teach me to read this:
INFORMIX-4GL by Example
Version 4.1
July 1991
Going to check now if any updated text exists, but would still appreciated more help in solving this problem. Do you think reverting to a previous snapshot before Informix was installed and not opting for the ol_informix1170 database to be included could be a possible solution? I wouldn't really see that it would be, but what do I know.
Many many thanks for your continued time and effort.
Regards,
Neill
Update 3
So I see indeed the document I was reading is ancient. I have found an updated one (2002) which uses a different script (dbaccessdemo7).
I tried running that, have run into an error, but tomorrow is another day.
For now I am going to mark this as solved because of the bug detected and resolved. I am not going to put more time and effort into sqldemo.
Thank you so much, and if I struggle with dbaccessdemo 7, I will post a new question.
Regards,
Neill
The sqldemo script won't create a new server; it may clobber your existing database (a single server may house multiple databases; indeed, there are 4 sys* databases created when a server is initialized) but it won't harm your server otherwise.
Probable cause of the error
The normal problem with invalid locales is that you've not set $INFORMIXDIR. You need $INFORMIXDIR set unless /usr/informix is (a symlink to) the correct location. You also need $INFORMIXSERVER set, and you usually need $INFORMIXDIR/bin on $PATH. Strictly, $INFORMIXSERVER is the only mandatory variable; in practice, you worry about the other two too.
The $INFORMIXDIR setting is used to locate the locale information (which is found in $INFORMIXDIR/gls) and the message files (which are found in $INFORMIXDIR/msg).
Note that CP1252 is a Windows code page. Normally on Unix, you'd either not set CLIENT_LOCALE or DB_LOCALE, or you could set them to:
export CLIENT_LOCALE=en_us.8859-1
export DB_LOCALE=en_us.8859-1
or you can choose another more appropriate (to you) locale. The 8859-15 locale includes the Euro symbol, for example, or the utf-8 locale dictates UTF-8 in the database. But, for initial debugging, stick with the 8859-1 locale, aka 819 or 0333 (all based on the IBM CCSID). If it doesn't work with 8859-1, then we have one set of problems; if it works with 8859-1 but not some other codeset or locale, then we have a different set of problems.
Follow-up info if the solution above fails
If that isn't the trouble, then I'll ask for some more details — notably, your Informix environment as reported by the dbenv script below:
: "#(#)$Id: dbenv.sh,v 2.11 2007/09/02 00:18:58 jleffler Exp $"
#
# Printout INFORMIX database environment
informix1="DB[^=]|DELIMIDENT=|SQL|ONCONFIG|TBCONFIG|INFOR"
informix2="ARC_|CLIENT_LOCALE=|GL_|GLS8BITSYS|CC8BITLEVEL|ESQL|FET_BUF_SIZE="
informix3="INF_ROLE_SEP=|NODEFDAC=|ONCONFIG|OPTCOMPIND|PDQ|PSORT"
informix4="PLCONFIG|SERVER_LOCALE|FGL|C4GL|NE_"
informix5="TCL_LIBRARY|TK_LIBRARY"
informix="$informix1|$informix2|$informix3|$informix4|$informix5"
system="COLLCHAR=|LANG=|LC_|LD_LIBRARY_PATH(_64)?=|PATH=|SHLIB_PATH="
jlss="IXD(32|64)?="
env |
egrep "^($informix|$system|$jlss)" |
sort
It's an old script; that's why the shebang is missing.
Second set of diagnosis
I was hoping for the complete output of the dbenv script; it is surprising how often something shows up. However, given what you've said, it is likely to be OK.
The INFORMIXSERVER setting sounds fine.
I'm struck by the LANG=en_US.UTF-8 setting; Informix does pay attention to $LANG and the $LC_* variables (that's why dbenv prints those out). That may be a factor in the problem. However, I would have expected CLIENT_LOCALE and SERVER_LOCALE to deal with that if it was the problem. Also, on my Mac, I have LANG=en_US.UTF-8 and yet I can connect to (8859-1) databases OK.
This is beginning to look like an install problem...or sqldemo problem...
I transitioned from a Mac to a RHEL 5 (archaic) x86/64 machine, and tried running sqldemo over there:
$ dbenv

$
Oh yeah? No; my locales are fine, thank you!
Well, so be it...I can reproduce your problem! That's step 1. Step 2 is to look at the expletive deleted script.
PRODUCT=sql
DEMOFILE=sqldemo
DEFLANG=en_US.8859-1
INFORMIXDIR=${INFORMIXDIR:=/usr/informix}
INFENV=$INFORMIXDIR/bin/infenv
CONVLOC=$INFORMIXDIR/bin/convloc
if [ $# -gt 0 -a "X$1" = "X-e" ] ; then
LOCALE=$DEFLANG # -e means en_US.8859-1 required
shift
else
LOCALE=`$INFENV DBLANG` # get DBLANG value
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV CLIENT_LOCALE` # try CLIENT_LOCALE instead
if [ "x${LOCALE}" = "x" ]; then
LOCALE=`$INFENV DB_LOCALE` # finally default to DB_LOCALE
fi
fi
fi
if [ "x${LOCALE}" = "x" ]; then
LOCALE=$DEFLANG # finally default to DB_LOCALE
fi
export LOCALE
if [ "x${DEMOPATH}" = "x" ]; then
echo "Invalid Locales set !!"
else
exec $INFORMIXDIR/demo/$PRODUCT/$DEMOPATH/$DEMOFILE $*
fi
exit $?
Note that test for ${DEMOPATH}; note that DEMOPATH is not set in the script. So, we've got to get it set. What to? Well, ls $INFORMIXDIR/demo/sql shows that there are various locale-specific sub-directories (en_us,
ja_jp,
ko_kr,
th_th,
zh_cn,
zh_tw) and under the en_us directory there's 0333 (only).
Please run:
DEMOPATH=en_us/0333 sqldemo stores2t -log
This more or less worked for me — I believe it would work for you. I have a slightly unusual setup in that I have just I4GL (p-code and c-code) and ISQL in the $INFORMIXDIR; the server is run out of a different directory. This means I don't have server utility programs like dbload (specifically) in $INFORMIXDIR/bin. When the sqldemo script tried to load the data with dbload, therefore, it failed for me. It would work for you because you have all the Informix software in a single directory. To add insult to injury, it runs the dbload program by explicit path, so I can't futz my PATH to make it available.
This should get you going. I have a bug to report...it is CQ idsdb00244894.
I'm sorry that you ran into so much trouble. You shouldn't have done so.

Improve this question
For debugging purposes in a somewhat closed system, I have to output text to a file.
Does anyone know of a tool that runs on windows (console based or not) that detects changes to a file and outputs them in real-time?
I like tools that will perform more than one task, Notepad++ is a great notepad replacement and has a Document Monitor plugin (installs with standard msi) that works great. It also is portable so you can have it on a thumb drive for use anywhere.
For a command line option, PowerShell (which is really a new command line) has a great feature already mentioned.
Get-Content someFile.txt -wait
But you can also filter at the command line using a regular expression
Get-Content web.log -wait | where { $_ -match "ERROR" }
Tail for Win32
Apache Chainsaw - used this with log4net logs, may require file to be in a certain format
When using Windows PowerShell you can do the following:
Get-Content someFile.txt -wait
I use "tail -f" under cygwin.
I use BareTail for doing this on Windows. It's free and has some nice features, such as tabs for tailing multiple files and configurable highlighting.
Tail is the best answer so far.
If you don't use Windows, you probably already have tail.
If you do use Windows, you can get a whole slew of Unix command line tools from here. Unzip them and put them somewhere in your PATH.
Then just do this at the command prompt from the same folder your log file is in:
tail -n 50 -f whatever.log
This will show you the last 50 lines of the file and will update as the file updates.
You can combine grep with tail with great results - something like this:
tail -n 50 -f whatever.log | grep Error
gives you just lines with "Error" in it.
Good luck!
FileSystemWatcher works a treat, although you do have to be a little careful about duplicate events firing - 1st link from Google - but bearing that in mind can produce great results.
Late answer, though might be helpful for someone -- LOGEXPERT seems to be interesting tail utility for windows.
Try SMSTrace from Microsoft (now called CMTrace, and directly available in the Start Menu on some versions of Windows)
Its a brilliant GUI tool that monitors updates to any text file in real time, even if its locked for writing by another file.
Don't be fooled by the description, its capable of monitoring any file, including .txt, .log or .csv.
Its ability to monitor locked files is extremely useful, and is one of the reasons why this utility shines.
One of the nicest features is line coloring. If it sees the word "ERROR", the line becomes red. If it sees the word "WARN", the line becomes yellow. This makes the logs a lot easier to follow.
I have used FileSystemWatcher for monitoring of text files for a component I recently built. There may be better options (I never found anything in my limited research) but that seemed to do the trick nicely :)
Crap, my bad, you're actually after a tool to do it all for you..
Well if you get unlucky and want to roll your own ;)
Yor can use the FileSystemWatcher in System.Diagnostics.
From MSDN:
public class Watcher
{
public static void Main()
{
Run();
}
[PermissionSet(SecurityAction.Demand, Name="FullTrust")]
public static void Run()
{
string[] args = System.Environment.GetCommandLineArgs();
// If a directory is not specified, exit program.
if(args.Length != 2)
{
// Display the proper way to call the program.
Console.WriteLine("Usage: Watcher.exe (directory)");
return;
}
// Create a new FileSystemWatcher and set its properties.
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = args[1];
/* Watch for changes in LastAccess and LastWrite times, and
the renaming of files or directories. */
watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite
| NotifyFilters.FileName | NotifyFilters.DirectoryName;
// Only watch text files.
watcher.Filter = "*.txt";
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnChanged);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
// Begin watching.
watcher.EnableRaisingEvents = true;
// Wait for the user to quit the program.
Console.WriteLine("Press \'q\' to quit the sample.");
while(Console.Read()!='q');
}
// Define the event handlers.
private static void OnChanged(object source, FileSystemEventArgs e)
{
// Specify what is done when a file is changed, created, or deleted.
Console.WriteLine("File: " + e.FullPath + " " + e.ChangeType);
}
private static void OnRenamed(object source, RenamedEventArgs e)
{
// Specify what is done when a file is renamed.
Console.WriteLine("File: {0} renamed to {1}", e.OldFullPath, e.FullPath);
}
}

Snake Tail. It is a good option.

Just a shameless plug to tail onto the answer, but I have a free web based app called Hacksaw used for viewing log4net files. I've put in an auto refresh options so you can give yourself near real time updates without having to refresh the browser all the time.
Yeah I've used both Tail for Win32 and tail on Cygwin. I've found both to be excellent, although I prefer Cygwin slightly as I'm able to tail files over the internet efficiently without crashes (Tail for Win32 has crashed on me in some instances).
So basically, I would use tail on Cygwin and redirect the output to a file on my local machine. I would then have this file open in Vim and reload (:e) it when required.
+1 for BareTail. I actually use BareTailPro, which provides real-time filtering on the tail with basic search strings or search strings using regex.
To make the list complete here's a link to the GNU WIN32 ports of many useful tools (amongst them is tail).

Surprised no one has mentioned Trace32 (or Trace64). These are great (free) Microsoft utilities that give a nice GUI and highlight any errors, etc. It also has filtering and sounds like exactly what you need.
Here's a utility I wrote to do just that:
It uses a FileSystemWatcher to look for changes in log files within local folders or network shares (don't have to be mounted, just provide the UNC path) and appends the new content to the console.

#echo off
set LoggingFile=C:\foo.txt
set lineNr=0
:while1
for /f "usebackq delims=" %%i in (`more +%lineNr% %LoggingFile%`) DO (
echo %%i
set /a lineNr+=1
REM Have an appropriate stop condition here by checking i
)
goto :while1
A command prompt way of doing it.
FileMon is a free stand alone tool that can detect all kinds of file access. You can filter out any unwanted. It does not show you the data that has actually changed though.
I second "tail -f" in cygwin. I assume that Tail for Win32 will accomplish the same thing.

I did a tiny viewer by my own:
