selecting specific command prompt from multiple command promt

ayush has asked for the wisdom of the Perl Monks concerning the following question:

Hello Monks,

I am trying to write a perl script that would access and execute command in another command prompt.

Explanation: Windows command prompt 1 is executing a perl script , and executes a system command that opens another command prompt ,with some set environment variables , now once the other prompt is opened i want to execute different sequence of commands in the newly opened prompt,

Is there any way where i can search process (in this case a command prompt) , and then input that process with a .bat file,

Tried something like

$pid = open("$nameofprompt" , "|$args"); but NO luck,

unfortunately the platform is windows, any kind of help would be a help,

thanks .

I'm not sure this is a Perl question: can you do what you've described from the CLI? If so, `system` or backticks might offer an approach whereas `open` is -- as `perldoc -f open` will tell you -- for opening a file; not for executing it. If I've misconstrued your question or the logic needed to answer it, I offer my apologies to all those electrons which were inconvenienced by the creation of this post.	[reply] [d/l] [select]

This smacks of an XY Problem. Can you bring the problem up one level?	[reply]

Hi, not really sure what you want to do, but you can definitely launch another command prompt process from your Perl script, including launching a command.bat or another Perl script within that new command prompt. For example: # Outer Perl script # do something and set $arg to something my @inner_script_result = `perl ./inner_script.pl $arg`; # ... [download]	[reply] [d/l]

Hey buddy, I had this same project way back before, check out my post, It got answered. http://perlmonks.org/?node_id=1064931 I wanted to be able to run 2 cmd.exe in the background that I can continuously monitor, and occassionally send commands to any of the 2 cmd.exe and read its output (reply) when it replies. I hope this helps! Mabuhay Civil Engineers! :D	[reply]
