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. python-3.x), 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

history -d 511works as expected, thenhistory -d 512deletes what used to be 513, and 512 remains in the history as command 511. Hope that makes sense.$xeach time through the loop, I'm deleting$1. So it first deletes 511,and 512 becomes 511. Then it deletes 511 again, and so on.for i in... andhistory -d $iand got the results I described in my comment above. Using $1 this absolutely is correct as stated in your original answer.
