Getting information about dead processes

Getting information about dead processes

[Leah Neukirchen]

Hi,

in $? or $status we can find the exit code of the last process, but I
can't see a way to find more detail about the exit status.  The job
layer has access to WIFSIGNALED and WTERMSIG, and displays if a
process died due to a signal.  How can I access this data from a zsh
script/interactive session?

Thanks,

If the process died due to a signal, then 128 is added to the signal
value.  So 130 indicates a process died to to signal 2, almost certainly
SIGINT.  The status value itself would be irrelevant, as the process
didn't get the chance to return one.
