Re: eval a command

in reply to eval a command

The following code exists and the fork prints "Hello World" after the required 5 sec.

use strict   ;
use warnings ;

my $cmd = 'sleep 5; print "Hello World\n";' ;
my $pid = fork();
if (defined $pid && $pid == 0) {
    # child
    
    eval $cmd;
}                

exit 0;

OS, Perl version and details on the command you are trying to execute might help

[Xantara]

All the commands that I run are subroutines of perl modules only. 
Execution of the $cmd, calls userdefined perl module API. In my case $mci->Do();

OS - Windows XP 
Perl Version 5.6

If you can update from 5.6 its probably a good idea.

On the other hand did you try to directly call that function and see if that works. Also why not just call these functions instead of using eval?

5.6 is over ten years old, seriously consider upgrading if at all posible.
