Try crond --help:
/ # crond --help BusyBox v1.24.2 (2016-06-22 17:51:28 GMT) multi-call binary. Usage: crond -fbS -l N -d N -L LOGFILE -c DIR -f Foreground -b Background (default) -S Log to syslog (default) -l N Set log level. Most verbose:0, default:8 -d N Set log level, log to stderr -L FILE Log to FILE -c DIR Cron dir. Default:/var/spool/cron/crontabs
I've been looking & this is the most information I can find about this...
for the crond -fbS -l N -d N -L LOGFILE -c DIR
it says -l
has options from 0 to at least 8 with 0 giving the most detail, it then has -d
that maybe has the same scale, but is it -d=log to stderr? so, for example if I ran cron -fbS -l 2 -d 0 -L /var/log/cron.log
would it log to the foreground, background, & syslog with level 2 & log to STDERR with verbose log (0) while logging what to /var/log/cron.log
? Would it be the level set as -l
?
Whoa... You mean this thread, my comment, spawned a patch upstream to BusyBox?! Niiiiiiice. Thanks @jsarenik !
@eduncan911 My pleasure :)

Do you really think people know
file.sh
will not be executed ? Moreover not executed on Alpine but executed on Debian ?I'm unfortunately for me - and the time I spent - not part of these people.
