QUESTION
When executing a python script with crontab, the script lacks environment variables.
The script calls an executable which some Linux distributions ship under /usr/bin
and other under /sbin
.
subprocess.check_output()
doesn't account for this.
Can I assume that which
is always under /usr/bin/which
?
Is Popen
the better alternative with env=os.environment.copy()
?
I've tried with shell=True
and sh -c
in the crontab.

It probably depends on which cron
we're talking about. Vixie cron sets PATH
, HOME
and SHELL
and LOGNAME
.
Any but LOGNAME
can be overridden in /etc/crontab
or your own crontab
file. So set up a proper PATH
in your crontab file.
