ed doesn't handle SIGPIPE and so ungracefully exits upon receiving it.
AFAICT, that is compatible with POSIX: https://pubs.opengroup.org/onlinepubs/9799919799/utilities/ed.html "The ed utility shall take the standard action for all signals"
While you're at it, you might want to revisit your file I/O. For example, [...] * r ! exit 1 ! exit 1: Success Cannot close input file
Thank you very much for reporting this. The misbehavior above is caused by an incomplete attempt at detecting a nonzero exit status of the shell command. I have reverted to ignoring the exit status. The fix will appear in ed 1.21 in a few days.
Best regards, Antonio.
