using
time sleep 1
yields:
$ time sleep 1
real 0m1.005s
user 0m0.001s
sys 0m0.001s
is there a command I can use to print the exit code of sleep
or whatever command I want to run?
Something likes:
$ log-exit-code sleep 1
perhaps this sufficient?
sleep 1 && echo "$?"

In my testing so far this has worked:
command && echo "$?" || echo "$?"
Just tells it to echo the exit code if it succeeds or if it fails.
As Sato pointed out below this is essentially the same as:
command; echo "$?"
One thing that could make the and/or command worthwhile is something like:
command && echo "Success! Exit Code: $?" || echo "Failure! Exit Code: $?"
If you need your script to act on the exit code as is Olivier's concern, it is a non issue. Your script could look something like:
