2 programs as 2 processes

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

Hi. Is it possibly in Perl to EXECUTE 2 PROGRAMS from ONE in that way, that the 2 programs were working at the same time - 2 PROCESSES ??? I made Perl program: system("c:\\valeriy\\program2\\pr1.pl"); system("c:\\valeriy\\program2\\pr2.pl"); But It executes FIRST, then WAITS, than executes 2ND. I need then working at the same time, paralelly. :) Hope here are Perl professionals.

Note that the originaly poster appears to be using a Microsoft "operating system" which means that fork probably isn't the best choice. This is because prior to Perl 5.6.0, fork() didn't work. With Perl 5.6.0, fork() might work for this but it is very new and appears to be quite buggy in some situations. Personally I'd use `system(1,"script")` to prevent the calling script from waiting. - tye (but my friends call me "Tye")	[reply] [d/l]

Take a look at Run commands in parallel and see if it can do what you want.	[reply]
