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
my_func() { ( set -x; my_commands; ...; ) }; set +x; my_func; return_code=$?; set -x. It's dumb, but maybe more compact, and still prevents the parent script from prematurely existing?waitexit status 127 (i.e. the background job has already exited by the timewaitis called) needs to be treated as 0. Of course, you'd lose the detection of a status 127 in the inner command, but that's the lesser of two evils, I guess.-ein the generic run function? run shouldn't need it, and without it, it would more flexible by letting the caller choose (plus simpler).
