Bash Version: 5.1 Patch Level: 16 Release Status: release Description: This script writes "foo" to bar rather than stdout as I'd expect. It's triggered by the "if" statement (which doesn't even cause running in a subshell, so it's not that). #!/bin/bash set -e trap 'echo foo' 0 #false > bar # "foo" written to stdout correctly if true; then false; else false; fi > bar # "foo" written to bar
