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

execvlbecause jaikit usesexecvand I am having a hard time findingexecvl- did you meanexecl?execl, sorry./sbin/reboot -> /bin/systemctl? Is this the only way an executable can detect its invocation ?argv[0](a program could in principle findargv[0]in a different way, but that would still be the information passed by the invoking process inargv[0]).
