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
lang-bash
bash, if you intercept SIGINT and exit normally in a child process, then the script won't exit upon^C(same for SIGQUIT vs ^\ ). To work around that, you'd need to replace thatreturnwith akill -s INT <mypid>(where<mypid>is the pid of the subshell (but beware not all shells run subshells in a child process))./dev/tty), you may want to issue the prompt there as well instead of stdout which may be redirected (or maybe stderr).stty "$t"twice c) it doesn't work inyash. I've tried to do something that work in as many shells as possible (thence the awkwardreturn), but the results are still less than stellar ;-) A version which do WCE correctly but only work in bash would not catch theINT,QUITandTERMat all, but rely on bash running theEXITtrap even when terminating because of a signal.
