Is there a way to catch a failure in piped command

问题:

This question already has answers here:

Catching error codes in a shell pipe (4 answers)

Closed 6 years ago.

Here's an example of what I'm trying to achieve:

#!/bin/bash
set -e    # abort if error
...
command1 2>&1 | command2
...

And I notice that sometimes command1 fails but command2 does not and the shell script happily continues... if I did not have to use the pipe here, the set -e would have been sufficient but now it does not work with the pipe there...

Any thoughts? Thanks

Since you are using bash, other than set -e you can also add set -o pipefail to get the results you want...
