It's very simple. Cron's environment is very sparse. You need to set and export any needed environment variables before calling Perl. In your case, PATH needs to be set to include the location of Perl.

1. $min is undefined. passing that to localtime may cause *strange* results

why use POSIX?

# arch_date=`perl -e'@l=localtime;printf"%02d-%02d-%4d",$l[3],$l[4]+1,$l[5]%100'`

If you *realy* want POSIX:

# arch_date=`perl -MPOSIX=strftime -e'print strftime"%d-%m-%y",localtime'`

Note that POSIX is slow.

Enjoy, Have FUN! H.Merijn

That is because you did not give full path of perl. Give it and you would be fine.

You can't directly edit the environment of cron but you can do something like this in the script called by cron:

#!/usr/bin/sh

export PATH=${PATH}:/opt/perl/bin

xxx=$(perl ....)

You may also need to add -Idir arguments to the Perl invocation so that it knows where to find any needed modules.
