So for running cron jobs with a version of Perl installed by Perlbrew, I
just needed to add the following lines at the start of cron script:
PERL5LIB=/home/teddy/perl5/perlbrew/perls/perl-5.14.2/lib/site_perl/5.14.2:/home/teddy/perl5/perlbrew/perls/perl-5.14.2/lib/5.14.2
PATH=/home/teddy/perl5/perlbrew/bin:/home/teddy/perl5/perlbrew/perls/perl-5.14.2/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
That's all.
The advantage is that when you'll install a new version of Perl with
Perlbrew, you will just need to change 2 lines in cron, and not all the
Perl programs.
Which you have to do for every cron script. And you're not using perlbrew;
you're bypassing it and doing one of its task manually. To use perlbrew in
your cron scripts, replace the above two lines with:
# perlbrew
if [ -e /home/teddy/perl5/perlbrew/etc/bashrc ]
then
source /home/teddy/perl5/perlbrew/etc/bashrc
fi
Now, after you do a `perlbrew switch ...` the next time the cron script
starts, it will use the new perl. Which is what using perlbrew means; the
ability to change the perl version without changing all your scripts.
I tried that, but it gives an error:
"/tmp/crontab.YkxBxg/crontab":6: bad minute
the if [ ... ] line doesn't seem to be accepted in cron jobs.
So without this feature, yes, we might need to change a few chars in 2 lines
in every cron script, but a user has only a single cron job so it is not
such a big issue.
