How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. shell-script), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you

sleepand there is no trap for SIGINT in the shell, the shell kills itself with SIGINT at the very end because of WCE; in effectexit 0does not matter. I'm not sure why we getIn exit_trap $?=0though. Waiting for a good answer.In exit_trap $?=0seems to be the exit status of thetrap exit_trap EXITcommand itself ... Shell seems to die after SIGINT leaving out some unfinished tasks like updating$?with the last status ... Send SIGQUIT instead with Ctrl+\\ and that should terminate differently ... Trapping SIGINT intercepts it so the shell terminates differently byexit 1in your function and not because of SIGINT.
