I have a perl script which creates a PDF file from data in a table.
This morning I was making some modifications to it, and it stopped
working with a "Couldn't get mydata handle" error. I restored the
original file, but it still fails with that error, even after
rebooting the machine. Here is the

Yeah I had thought about the exec(), but being its a library I would
have no idea what to exec...they could tell me but

Hi,
Windows requires you to use double quotes in place of single quotes. Saving to
a file and executing it is the only way that is cross-platform, I suppose.

Hello,
Sometimes, my sql is running for a quite long time, e.g. 1 hour
The perl script will warn "DBD::mysql::st execute failed: MySQL server

You need to test the return of eval itself to be sure.
Example:
perl -wle '
die "An error: ", $@ || "whoopy"
if !eval{ asub(); 1 };
sub asub{ my $x = bless {}, "main"; 1 / 0 }
sub DESTROY{ $@ =

Since I can't really rely on a fix time run time basis, this doesn't
make too much sense either, Instead of that i thought i'd rather
execute a littler bash script from the crontab that's like:
#!/bin/bash
if [ -e /var/run/myPIDfile ]
then
echo "script still running";
else

q// is single quotes, qq// is double quotes.
Thanks Philip for the wonderful explanation.
And thanks John, your code worked like a breeze both on Windoze & *Nix :)
And good thing is it provided the solution to insert a new-line character
which was not present in my Windoze code.
One question though in following code -

I may never have been on linux if that had been the case.
