I'm writing a shell script that's supposed to function on various different distributions, some of which are using
busybox and some are not.
This script uses the
timeout command to figure whether a command it executed ran longer than
<time> or not. In the case of distributions which use the
timeout this is no problem because when
timeout had to kill a command it always returns
124, so that's simple.
My problem is that when I run the same on
Alpine Linux (which uses busybox ) then the exit status is
0 after timeout had to kill the command, but when I use the
timeout command from the
busybox package in Ubuntu it exits with
Why do the two
timeout commands, which are both from
busybox, give me a different return value?
Is there any consistency or rule in that which I can use to determine whether the command has timed out or not?
