in reply to Perl script runs through Cron but does not generate files

Here is a piece of code for you:

#!/usr/bin/perl -w use strict; my $mode=shift @ARGV; my $logfile=sprintf("/tmp/%s-env.txt",$mode); open FOUT,"> $logfile" or die "$logfile: $!"; foreach my $key ( sort keys %ENV){ printf FOUT "%s = \"%s\"\n",$key,$ENV{$key}; } close FOUT; system(sprintf "umask >> %s",$logfile); system(sprintf "id >> %s",$logfile); system(sprintf "pwd >> %s",$logfile); exit(0);
Don't forget to  $ chmod 755 /path/to/my/script/above.pl so it can run. First run it as a "batch" job
$ echo "/path/to/my/script/above.pl ascron" | at now
which will be the same environment as a cronjob would be. Then run it from the command line:
$ /path/to/my/script/above.pl ascmdlin
then check the differences:
diff /tmp/ascron-env.txt /tmp/ascmdlin-env.txt
and that should help you rule some stuff out.

Typically the difference between command line and cron has to do with permissions or environment being different. It ain't rocket science.
