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. windows-7), 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
ps aux | grep shutdownis similar to jobs; however, this doesn't push out the global shut down message.pscommand just shows processes, so it's not an alternative. Try this:ps aux | grep shutdown | grep -v grepand I bet that comes back with nothing. Essentially when you grep, that is also a process, so you're probably just getting your grep process returned and not the shutdown process. The-v grepsays omit the grep process.apt-cache search jobsand see what packages come back, maybe there is something that you can install that is the jobs command itself or similar. Or just use Cron.
