An obvious improvement is to notice that \s contains \n. And also that 'use Env' is completely useless in this case.	[reply]

Thanks, will I be able to access env variables if my perl code gets run from cron?	[reply]

Yes and no. You can read an environment, but as cron jobs run their own environment, you need to load the environment you want. See Get default login environment.	[reply]

You can access environment variables in a script run as a cron job but take note that cron jobs often have only a sub-set of the environment available to a user shell. For instance, you will likely have a minimal `$PATH` under cron. It might be worth writing a small script to dump the environment to a file then run it as a cron job to see what's available. I hope this is helpful. Cheers, JohnGG	[reply] [d/l]
