Hi there. I've wrestled with this for days now, and haven't gotten anywhere. I'm using Perl to make web-based glue-code for an import (of log files) script. Summary of the problem is: "after a long running process system("import $file"), my system("mv $file /tmp/trash") isn't working" Here are more details...

Scenario is: 

/var/log/newlogs/One_Log_Dir/log.txt, screenshots.jpg, etc.

So... put up a web-page with checkboxes and the output of: 

@files = `find /var/log/newlogs -name log.txt -maxdepth 2`

[download]
(remember, this is glue-code, so I'm not using / learning readdir / opendir, etc yet).

...and after a submission (where $cgi->param('logs') is filled with checkboxed selected items...) 

for my $log ( @logs )
{
  add_and_trash( $log )
}

[download]

Where add_and_trash() is something like: 

sub add_and_trash
{
  my ($name) = @_;

  my $newname = `convert $name`;
  print "<hr>\n";

  my $cmd1 = "/tools/addbundle.pl $newname";
  print $cmd1. "<hr>\n";
  system( $cmd1 );  # can take ~2-3 minutes

  my $cmd2 = "mv $newname /tmp/trashed";
  print $cmd2. "<hr>\n";
  system( $cmd2 );
}

Can anyone see any problems? Every single function call is being called correctly. If I take the copy/paste of the print $cmd's and paste them manually into a bash session, everything works, it's only when run from the perl front-end that it bombs.

`whoami` reports back 'rames', not 'nobody'. Any ideas / assistance would be welcome. Sorry for chopping apart the script (it's long and boring, otherwise), hopefully my perl-fu is strong enough that I didn't make any syntax errors while paring it down.

I've done reading with perldoc perlops (for ``), and perldoc -f system, but just can't figure out why when *I* copy and paste the commands by hand it works, but perl (perl/cgi running through apache) can't get it working.

Assistance is appreciated, I'll respond with more details if there are parts that I'm missing.
