Hi, The following example returns the exit status of the last command in a pipe. I'm wondering if there is a way to inherent non-zero exit status using pipe. That is, if there is any command in a pipe that return a non-zero status, I'd like the whole pipe return a non-zero status.
$ cat main.sh #!/usr/bin/env bash echo abc 1>&2 echo abc 1>&2 echo abc 1>&2 echo abc 1>&2 echo abc 1>&2 exit 1 $ ./main.sh abc abc abc abc abc $ echo $? 1 $ ./main.sh |head -n 3 abc abc abc abc abc $ echo $? 0 -- Regards, Peng -- To unsubscribe from this list: send the line "unsubscribe dash" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
