Release Status: release
Description:
I am not sure if this is a bug, or if this is correct behavior.
consider:
false | true
echo $?
0
If a command in a pipeline of commands fails, there appears to be no
way of knowing this. One alternate behavior to consider is to return
the exit status of the first command in the pipeline to exit with non
zero status.
The return codes are stored in the PIPESTATUS array:
$ false | true | false | true
$ printf "%s\n" "[EMAIL PROTECTED]"
