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
-eis a thing. This even allows ctrl+arrow-key to skip words and keys like ESC or F-keys simply don't write anything now. One question about the history thing: How exactly does that work? I've never heard about this other than related to the .bash_history | I'm marking this as the accepted answer, even though it doesn't exactly filter escape sequences like asked, this is a way more elegant and compact solution.history -randhistory -wrespectively. If you do want to save the entry history between chat sessions, you could put them at the beginning and end of the script (but I'd recommend changing theHISTFILEvariable to something other than ~/.bash_history, so the chat history doesn't get mixed with your command history).
