# `head -n 1` should close stdout of the `Shell -c` command, which means the
# second echo should exit unsuccessfully and sigpipe.sh.out should not be
# created.

# Failing commands don't make the test fail, just an explicit `exit 1` does.
# So the test only fails if sigpipe.sh.out exists (since then `exit 1` runs),
# not if the `test` statement returns false.
