mispipe - pipe two commands, returning the exit status of the first
pipes two commands together like the shell does, but unlike
piping in the shell, which returns the exit status of the last command; when
using mispipe, the exit status of the first command is returned.
Note that some shells, notably bash
, do offer a pipefail option, however,
that option does not behave the same since it makes a failure of any command
in the pipeline be returned, not just the exit status of the first.
The exit status of the first command. If the process terminated abnormally (due
to a signal), 128 will be added to its exit status.
