Is there a way to catch the failure in piped commands?

Question

Is there a way to catch the failure in piped commands?

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

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

And I notice that it command1

crashes sometimes , but command2 doesn't work and the shell script continues happily ... if I didn't have to use the pipe here set -e

would be enough, but now it doesn't work with the pipe there ...

Any thoughts? Thanks to

Since you are using bash, apart from set -e

, you can also add set -o pipefail

to get the results you want ...
