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
ps --no-headers -o cmd $(ps --no-headers -o ppid $$)replace everything in the above code, or only the code inhas_ancestor(){...}?kilein an environment with history disabled. That probably works, but it's inconvenient, and will only help if you remember to use it every time. (That said, if you meant using the environment changes instead ofset -o history, that might work also, but seems more round-about thanset -o history.) 2) See edit. It would probably be beneficial to learn enough shell to understand how both functions actually work rather than just trusting what I wrote. 🙂ps --no-headers -o cmdwill only work if the command-line used to invoke Kile is exactlykile, not/usr/bin/kile,kile <args...>, or a combination thereof. The version in the edit retains robustness against these, only discarding the test against any ancestor process. If you were to write it inline, you would write something likeif [ $(ps --no-headers -o cmd $(ps --no-headers -o ppid $$)) == kile ]instead of theif ...shown in the Answer, but mind the caveats in the beginning of this comment.set +o historyinstead ofset -o history? digi.ninja/blog/hiding_bash_history.phpkile.
