I was wondering how, if possible I can parse the QUERY_STRING in a .bat CGI script... like so:
Request:
QUERY_STRING=namebox=john%20doe&passwordbox=myPasscode
What I want:
set namebox=john doe && set passwordbox=myPasscode
thanks all, C.
for /f "tokens=1-3 delims=&%20" %a in ("%QUERY_STRING%") do set "namebox=%a %b" && set "passwordbox=%c"

I am writing a simple CGI program in lua. What I want to achieve is produce a response from CGI which enables a file to be downloaded from the browser. But I just can't print the data. I have no idea what's going on here. Here is the code below:
print("Content-Type: text/html; charset=UTF-8")
print("Content-Length:" .. sys.getenv("CONTENT_LENGTH"))
print("Content-Disposition:",'attachment;filename="backup.tar.gz"\n')
print("Content-Type:application/x-tar-gz\n\n")
file=io.popen("some command")
output = file:read('*a')
print(output)
--file:close()
The problem is I just can't print the output whose content is binary. I can see the type of output is string.
What is the problem? Please give some hints about it. Thank you.
ADD : I have no idea about this and Where is the issue. Let me put more info about the command I want run. But I don't think that matters.
Actually, I work in openwrt, the web server uhttpd. (No LuCI here)
The command is:sysupgrade -b - 2>/dev/null. This command is used to backup the config file. I want to write a CGI to download the backup file from the web.
But I can not print the output to the server. Even in the terminal(in lua IDE) I cannot print out the output except one or two messy code. But I can write the output to a file in terminal. Maybe it has some relationship with the content of out.
When I print the content line by line, it prints some, but not all of it. After I download the file. I can't open it.
print("Content-Disposition:",'attachment;filename="backup.tar.gz"\n')
print("Content-Type:application/x-tar-gz\n\n")
I think you have way too many new lines. First of all, you can newline in Content-Disposition and this is in addition to the newline that print adds, which ends the headers and makes Content-Type a part of the payload (which breaks the content). You also have two newlines in Content-Type where you only need one (as one is added by the print command).
I think something like this should work:
local file = io.popen("some command")
local output = file:read('*a')
file:close()
print("Content-Type: text/html; charset=UTF-8")
print("Content-Length: " .. #output)
print("Content-Disposition: " .. 'attachment;filename="backup.tar.gz"')
print("Content-Type: application/x-tar-gz\r\n")
print(output)
So I have a Ruby script (using Ruby because we have a library of pre-existing code that I need to use). From within Ruby I am using backticks to call Linux commands, specifically in this case the "mv" command. I am trying to move one file to another location but I keep getting the error message that x and y are "the same file" even though they are very clearly NOT the same file.
Here is the code in Ruby:
#!/usr/local/rvm/rubies/ruby-2.1.1/bin/ruby
masterFiles=[]
masterFiles << "/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY/Scans and DataOutput/Data/UH_HRA_SVY_DATA.txt"
masterFiles << "/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY_SPAN/Scans and DataOutput/Data/UH_HRA_SVY_SPAN_DATA.txt"
tm=Time.new.strftime("%Y%m%d")
masterFiles.each do |mf|
if File.exist?(mf)
qmf=39.chr + mf + 39.chr
`cat #{qmf} >> /tmp/QM`
savename=39.chr + \
"/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY/Scans and DataOutput/Data/DailyFiles/" + \
File.basename(mf).gsub(".txt","_"+tm) + ".txt" + 39.chr
`mv #{qmf} #{savename}`
end
end
The error that I get is this:
mv: `/mnt/datadrive/Data Capture/QualityControl/UH_HRA_SVY_SPAN/Scans
and DataOutput/Data/UH_HRA_SVY_SPAN_DATA.txt' and `/mnt/datadrive/Data
Capture/QualityControl/UH_HRA_SVY/Scans and
DataOutput/Data/DailyFiles/UH_HRA_SVY_SPAN_DATA_20140530.txt' are the
same file
If I change this line:
`mv #{qmf} #{savename}`
To this:
puts "mv #{qmf} #{savename}"
And then run the output, it works as expected.
I am pretty sure that this has to do with spaces in the path. I have tried every combination of double-quoting, triple-quoting, quadruple-quoting, and back-slashing I can think of to resolve this but no go. I have also tried using FileUtils.mv but get what is basically the same error worded differently.
Can anybody help ? Thanks a lot.
p.s. I realize it's entirely possible that I could be going about this in an entirely wrong-headed way, so feel free to point that out if so. However, I am trying to use the tools which I already have some knowledge of (cat, mv, etc) instead of re-inventing the wheel.
You could use FileUtils.mv
I often do aliases like so:
require 'fileutils'
def mv(from, to)
FileUtils.mv(from, to)
end
And inside the mv() method I do additional safeguards, i.e. if the file does not exist, if there is a lack of permissions and so forth.
If you then still have problems with filenames that have ' ' blank characters, try to put the file into a "" quote like:
your_target_location = "foo/bar bla"
I currently have an exported text file (output.txt) from a Clear-Case command that I need to parse. It looks like this:
Comparing the following:
R1.PROD.V1#\VOB_pvob
R2.PROD.V1#\VOB_pvob
Differences:
>> M:\ACME_PROD\src\ACME##
>> M:\ACME_PROD\src\ACME\file 2.txt##
>> M:\ACME_PROD\src\ACME\file 1.txt##
>> M:\ACME_PROD\src\ACME\file 3.txt##
What I would like to do is use the findstr command to filter the strings that are contained between the ">> " and "##" strings to get an output file that looks like this (with quotes if possible:
"M:\ACME_PROD\src\ACME"
"M:\ACME_PROD\src\ACME\file 2.txt"
"M:\ACME_PROD\src\ACME\file 1.txt"
"M:\ACME_PROD\src\ACME\file 3.txt"
I am new to writing batch files and so I don't exactly know where to start. I have managed to find code that can loop through the lines of a text file and separate code for the findstr command, but I get stuck trying to put it all together!
Best regards,
Andrew
Here you go
setlocal enabledelayedexpansion
for /f "skip=1 tokens=* delims=> " %%a in ('"findstr /r [\w^>*] output.txt"') do (
set line=%%a
set line=!line:#=!
echo "!line!" >>new.txt
)
The filtered strings will be outputted into new.txt.
I want to read a file a extract information from it based on certain tag. For example :
SCRIPT_NAME:mySimpleShell.sh
This is a simple shell. I would like to have this as
Description. I also want to create a txt file our of this.
SCRIPT_NAME:myComplexShell.sh
This is a complex shell. I would like to have this as
Description. I also want to create a txt file our of this.
So when I pass in this file to my shell script, my shell will read it line by line and
when it gets to SCRIPT_NAME, It extract it and save it in $FILE_NAME, then starts writing
the description to a file on disk with $FILE_NAME.txt name. And It does it until It reaches the end of file. If there is 3 SCRIPT_NAME tag, then it creates 3 description file.
Thanks for helping me in advance :)
Read the lines using a while loop. Use a regex to check if a line has SCRIPT_NAME and if so, extract the filename. This is shown below:
#! /bin/bash
while IFS= read -r line
do
if [[ $line =~ SCRIPT_NAME:(.*$) ]]
then
FILENAME="${BASH_REMATCH[1]}"
echo "Writing to $FILENAME.txt"
else
echo "$line" >> "$FILENAME.txt"
fi
done < inputFile
#!/bin/sh
awk '/^SCRIPT_NAME:/ { split( $0, a, ":" ); name=a[2]; next }
name { print > name ".txt" }' ${1?No input file specified}
I have the following values in a DOS batch file (for example...):
..\Apple\Jones
..\Banana\Smith
..\Pear\Wilson
I need to extract the last name values ("Jones", "Smith", "Wilson") from each value. What one technique can I use that will always give me these substring values?
According to this topic : What is the best way to do a substring in a batch file?
I suggest you to use
%~n0
I already wrote a function for that. You give it any path and it returns you only it's filename or pathname. Works for any path: Url, Windows path, Unix path, etc...
Copy this function at the end of your batch script: (Instructions below)
rem ===========================================================================
:Name_From_Path
SetLocal
set _TMP_FOLDERNAME=%1
for %%g in ("%_TMP_FOLDERNAME%") do set _TMP_FOLDERNAME=%%~nxg
EndLocal & set _Name_From_Path=%_TMP_FOLDERNAME%
goto :EOF
rem ===========================================================================
Usage:
CALL :Name_Of_Path ..\Apple\Jones
ECHO %_Name_From_Path%
Result: Jones
