write to cmd and save output

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

dear monks

I'm in a fix. I run ActivePerl 5.8 on w2k (Sigh).
I need to launch a cmd , send to it some input BUT save all the output of the command to a variable for post processing. I have super-searched a lot and I was not helped so much.

I have tried IPC::Open3 IO::Handle IO::Capture::Stdout without hope..

I need to interact with a well known custom program of my company that run from cmd promp interactively..

any words will be apprecieted for this tipical -- node ;)

cheers from hot sunny roma Lorenzo*

If IPC::Open3 doesn't work, try IPC::Run3	[reply]

Dunno if this works on win32, but assuming you can do you postprocessing AFTER the command is run: `open CMD,"\|prog.exe >out.log" or die "$!"; print CMD "stuff"; close CMD; open LOG,"<out.log" or die "$!" while (<LOG>) { process($_); } close LOG;` [download] HTH, Joost `-- #!/usr/bin/perl -w use strict;$;= ";Jtunsitr pa;ngo;t1h\$e;r. )p.e(r;ls ;h;a;c.k^e;rs ";$_=$;;do{$..=chop}while(chop);$_=$;;eval$.;` [download]	[reply] [d/l] [select]

Update:Doh.. I missed the interactively part.. If you mean run an executable and capture the output, there are several ways to do this. $result = `mycmd.exe -param1 -param2`; or you could look at win32::process but you would have to do some clever STDOUT redirection.
