I do understand that removing the cat from the command line will then cause the error to be caught ($? is 127). My example is simple to keep the question clear. Using set -e and set -o pipefail with the cat... version won't cause $? to be 127. This problem came up when using gnu parallel to run commands in a file, some of which use process substitution.
