Piping command output to tee but also save exit code of command [duplicate]
You can set the pipefail shell option option on to get the behavior you want.
From the Bash Reference Manual:
The exit status of a pipeline is the exit status of the last command in the pipeline, unless the
pipefailoption is enabled (see The Set Builtin). Ifpipefailis enabled, the pipeline's return status is the value of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.
Example:
$ false | tee /dev/null ; echo $?0$ set -o pipefail$ false | tee /dev/null ; echo $?1To restore the original pipe setting:
$ set +o pipefail
You could run the mvn command and cache the exit code... I use the "false" command for my example.
$ { false ; echo $? > /tmp/false.status ; } | tee $logfile$ cat /tmp/false.status1That way you can use the status file content to make further decisions.
I'm curious now whether there is a more eloquent way to accomplish this.
