Sorry for the delay in responding, but I've been banging my head against this for awhile. I've tried what I believe'd is what you were telling me, but I'm a little dense. The system I'm on is redhat if that helps. Here is my ammended code after your suggestions, let me know what you think.

#!/usr/bin/perl -w

use strict;

chomp (my $curdir = `pwd`);
my $proc = '../delme.pl > proc.log 2>error.log';
my %kid;
for (1 .. 4) {
    chdir $curdir;
    do { mkdir "test$_" or die $! } unless (-d "test$_");
    chdir "test$_" or die $!;
    print "Launching: Process $_$/";
    defined(my $cpid = fork) or warn $! and next;
    $kid{$cpid} = undef, next if %kid;
    exec $proc;
    exit 0;
}

delete $kid{wait()} while %kid;

print "Done...$/";

I get no errors but only one instance runs. I need four independant instances running and as you can see by code they should each run in their own directory. The delme.pl is trivial, essentially just printing a line to STDOUT as well as STDERR, then sleeping for 25 seconds.

Thanks for your help!
