I've got an ant target ant server that runs a Java application which logs to the console. I need to run a new ant target ant server-gui which also logs to the console. But when I run ant server the logging prevents me from running any new ant targets.
When I enter ^c (which is the only way I know of to get out of situations like that) it kills the Java application. I need both to run. What keystroke will get me out of that "input" mode and able to run new terminal commands?
UPDATE: I haven't found a direct solution to getting out of that mode I mentioned, but opening a new tab/window in terminal does the trick. I can run as many any commands as I'd like that way. Still looking for a good solution to get out the "input" mode, though!
UPDATE 2: #abcdef pointed out another post that has an even more elegant solution.
There are a few ways to do this, assuming you are on *nix
1) Run the ant command with a & at the end to tell *nix to run the command in the background
2) Run the command with nohup at the beginning (https://en.wikipedia.org/wiki/Nohup)
3) when the process is running press ctrl-z then enter the command bg. This manually forces the command to run in the background
I hope this helps you out

I am looking for solution where I can set my javascripts with order and when each script would start it would be independent on previous scripts. So I can run just one script or group of them and it would be working same.
I find that I can create one script file and use #import keyword, something like this:
#import "AddStaticContentMissingName.js"
#import "AddStaticContent.js"
It's working and both scripts are running but second one starts where first one ends and that is what bothers me. I can set first one to end when the second one needs but I don't like it. I just one to script do what should test and then end. So is it possible to before each test restart application or something like that? I want to have UI testing automate as possible so what or you using? Or are you using another tool then UI Automation?
Bonus question: I was looking for solution how to run this from command line and/or with Xcode Server. I guess Xcode Server is problem but for command line there is a solution. Problem with solution which I found is that I isn't portable right? I don't have any way how can I add some script to my repository and if someone try use it there would be problems with paths. Example of command I found:
instruments \
-w your_ios_udid \
-t "/Applications/Xcode.app/Contents/Applications/Instruments.app/Contents/PlugIns/AutomationInstrument.bundle/Contents/Resources/Automation.tracetemplate" \
name_of_your_app \
-e UIASCRIPT absolute_path_to_the_test_file
If you want to reset the application between scripts, you need to do it yourself with a combination of app code and UIAutomation code. (Apple will be replacing Instruments with something that works better, but for now this is the only way.)
For example, if your application doesn't use the "shake" gesture for anything, you could use that to trigger a restart within your app (not closing it, just returning it to a known state). Then at the top of every UIAutomation script, you could just call the method for the shake gesture.
In the testing framework we wrote, we set up our own RPC channel to allow us to expose non-UI functionality (like resetting the app) to automation scripts. It really doesn't matter what system you use to make it happen, as long as you can reliably get the app to a known state.
I might be too late for this but it's totally possible to accomplish what you want. Basically, create a bash script (or any other script) and include the commands to run your two automation scripts:
#!/bin/bash
instruments -w <UDID> -t <template> <app> -e UIASCRIPT <script1>
instruments -w <UDID> -t <template> <app> -e UIASCRIPT <script2>
Run that and your app will restart after the first script creating a trace file per run.
I have the following problem: I have an ANT-task in Jenkins-CI that (apparently) needs access to OSX' window server (it needs to show a window). After doing some research, it appears that only the currently logged in user and the 'root' user (or SUDO) can access OSX' window server.
The ANT task (Adobe ADL) is one that actually 'runs' a build, so it has to popup a screen.
I'm on a macBook running OSX 10.7.something (Lion), Jenkins 1.487, Ant 1.8.4.
What i have tried so far:
to start with, tried the 'barebone' < exec > task to invoke ADL. Works, but getting error that means that Jenkins running as daemon (with homedir /Users/shared/Jenkins/Home) cannot access OSX' Window Server.
Run Jenkins as myself, by changing USER_NAME, GROUP_NAME, JENKINS_HOME in the jenkins launchd.conf file: https://wiki.jenkins-ci.org/display/JENKINS/Thanks+for+using+OSX+Installer
this gives a lot of errors/trouble, which i tried to solve in communication with the creator of the Jenkins CI but, unfortunately to no avail.
Try to have Ant run an < exec > task (running a shell script) in which i try to sudo with a password using this sneaky way of passing a password to the stdinput: echo < password > | sudo -S < command > which is really bad, but as i'm running Jenkins locally (not reachable from the outside of my LAN) it's np.
Tried to have Ant run an < exec > task, using a 'redirector' with as inputstring my password. also superbad, but yea, i just want it to work. which it did not.
Tried a Jenkins SSH plugin: didn't work. I could, however, SSH to my own localhost using terminal, thing is, i don't know what the Jenkins SSH was trying to do (how can i figure that out anyway?) so i don't know why it wouldn't work.
Tried to have Ant run an SSHEXEC task (which, after some hours, finally worked. Ant for mac is borked, something with optional .jar tasks not being re-named correctly or something) but i'm getting a "com.jcraft.jsch.JSchException: Auth fail" which i googled for, and can't seem to resolve. only applicable solution is to have sshd accept password auths, did that, still got the same error.
I think what i want to accomplish was NOT worth the 2 days that i spent so far on this problem, although i learned a lot. However, i just want this to work and will not accept defeat, yet :)
My question: have you had to solve a similar problem, how did you go about it? are there any other methods i can try to solve this problem? Is there a method mentioned that should JUST _WORK_ and i did something wrong?
[edit] I have decided to go with the Jenkins standalone app, as i think (for me) this is a nicer solution in total, as my laptop is not a build server. Also, the Jenkins app can start at startup so it actually acts as a local server.
Just a quick guess: if you don't want the interactivity of the script, and the script can do without it, you can try to set the headless mode on the java command-line:
-Djava.awt.headless=true
I have decided to go with the Jenkins standalone app, as i think (for me) this is a nicer solution anyway, as my laptop is not a (headless) build server. Also, the Jenkins app can start at startup so it acts as a server too.
Not sure why when I execute a Python tools like pip or nosetests inside powershell, a separate popup command line windows will show, execute my command, then disappeared. This is annoying because I can hardly see the executable output, especially the last few lines before the popup close.
I assume there are some setting I can change to stop the popup?
I am using Powershell 2.0 in Windows 7.
Powershell is not cmd.exe, and it has a different console interface. More than likely, your py tools are writing to a non-existent shell window. You may be able to get around this by using the following syntax:
cmd /c script.py
What you do when you execute the python scripts directly from the PS prompt is fire-off a DOS shell for the period of time it takes for the command to complete. Since there's no 'pause' implemented, the shell window closes when the command completes.
A test script
# tester.py, just a test
print "This is a test script, that is all."
Output in PS:
C:\src\python
{powem} [36] --> .\tester.py
C:\src\python
{powem} [37] --> cmd /c .\tester.py
This is a test script, that is all.

For someone has similar problem, please have a look at this answer, I think this solution eventually solved my problem. and in my case, I have to restart my computer to get it all working.
I have a two scripts in the Rails environment which have to run 24/7. I'm working on a remote server, so I need to start the scripts using ssh, which means I need to keep the ssh windows open all the time.
I'm searching for a simple way to run these scripts in the background so they aren't canceled as soon as I close the ssh connection.
I don't want to use screen. I think there must be simpler way to handle this. Isn't there?
I think the most basic solution would be nohup:
nohup myscript &> /dev/null &
You can disown a script:
ruby script.rb &!
STDOUT/STDERR are still attached to the current shell, but the ruby process isn't a child of the shell anymore, so it won't get killed if you close the terminal.
Check Daemons. It's a toolkit for converting a script to a controllable daemon.
You can use
runit
supervisord
For daemonizing
Or some ruby stuff: https://www.ruby-toolbox.com/#Background_Processing for background processing
I'm trying to modify a legacy Delphi 5 app so that it can be launched either from it's icon/via Explorer, or from the console (command-line). When it gets launched from the console, I want the program to detach itself from the console process, so that the console can continue to execute other instructions without waiting for my program to terminate.
I want to use it in a 'batch' file, such that I might have;
#echo off
rem step 1 - do some stuff here
rem
rem step 2 - launch my app
c:\myfolder\myapp
rem
rem step 3 - do some more stuff here
and that the console process moves on to step 3 straight after launching my app in step 2.
I'm sure I've done this before, many years ago, but I'm puzzled as to what exactly I did. I don't want to write a tiny console app 'launcher' for my main Windows app - I'm 95% sure that there was a way of doing this within a 'normal' Delphi GUI app.
I guess I could use vbscript or powershell or something to 'execute' my program with some kind of 'nowait' parameter but the client is familiar with batch files and I don't really want to upset the applecart by suggesting he change his scripts or install additional stuff - I'm making changes to the executable anyway and it would be great to tick this box for him too.
Anyone? :-)
I think the START command is the one you're looking for. It starts a process separately to the console and it's part of cmd.exe so no extra software required.
But I was of the opinion that GUI apps did this anyway. Maybe Delphi is different to MSVC.
Open up a console and type "start /?".
As itowlson states in the comments, GUI application do generally detach themselves. It's the actual cmd.exe shell doing trickery in that it waits for it to finish if it's running from a cmd file.
So "notepad" from the prompt will start it in the background but "notepad" within a cmd file will wait. Within the cmd file, you need to use:
start notepad.exe
or whatever your application is called (not notepad, presumably).
try: start "" c:\myfolder\myapp (with the empty quotes)
I think Microsoft has been solve this problem in Windows Power Shell.
In command prompt, even if you use "start ", you cant detach your process really from cmd. If you close the cmd, you will die, suddenly. But In windows Power Shell, you can detach your program or command from Power Shell as default.
So, if you prefer to use Windows Power Shell instead of Command Prompt, just do this:
PS: X:\> <your command>
Here's one way that I've found. It works quite cleanly and doesn't leave any extra cmd windows around (the recommendation to use start c:\myfolder\myapp does not work:
cmd /c dir && c:\myfolder\myapp
To quote the CMD help:
/C Carries out the command specified by string and then terminates
Note that multiple commands separated by the command separator '&&'
are accepted for string if surrounded by quotes.
Apparently it notices that the dir command terminates and exits, even though your app was launched on the same command. Chalk it up to one of Windows vagaries.
u should use the cd command example
cd/
cd myfolder
start myapp
exit
