cron job won't run

mt_arch_user · 2023-01-21 01:52:34

I have a job scheduled using crontab -e

45 17 20 * * storeBackupMount.pl -f /etc/storebackup.d/storebackupmount.conf

I have set the time and date for testing purposes. I is usually at 3AM on the first day of the month.

Where storeBackupMount.pl is a perl script that requires the configuration file storebackupmount.conf
If I run this command from the cli, it runs as it should.
If I set the time and date in the cron file, I get this result from sudo systemctl status cronie:

It shows the job is being called but can't be run.
I don't understand the <pod2text> part of the error.

https://man.archlinux.org/man/core/perl … t.1perl.en
The cron daemon lacks "/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl" in its $PATH, try

45 17 20 * * env PATH="$PATH:/usr/bin/site_perl:/usr/bin/vendor_perl:/usr/bin/core_perl" storeBackupMount.pl -f /etc/storebackup.d/storebackupmount.conf

You're my hero! When I grow up I want to be just like you!

Am I correct that when this process completes, the perl additions will be removed from the environment?
There is nothing in /usr/bin/site_perl. Am I missing something?
I'm thinking I should have seen a "file not found" message somewhere in one of the log files. Where would that be?

Thanks again!

env sets the environment, runs the give process and then terminates - nothing will be removed, but the context terminates w/ the subprocess (storeBackupMount.pl, or rather perl in this case)
/usr/bin/site_perl is canonically added to the path by perl in interactive shells, but by default empty - it's not relevant in the specific case, but might if some perl script relies on that path.
There's no "file not found", the error comes out of the perl script and the critical information is just "STDERR of <pod2text>:cannot exec"

Interesting.

I just use chaotic gods as my usernames (typically fitting the hostname)

Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.
