Required fields*

note that comma is a valid character in a filename, so anything using this could break if either or both of old and new directory names contain a comma. Actually, it's easy enough to deal with the new dir having a comma (just limit the field split to the first comma only), but not if the old dir has one...and not if you can't tell which one is supposed to have an embedded comma. Probably safest just to report an error if there are > 1 commas in the input and continue to the next line.cas– cas2019-09-28 02:51:33 +00:00Commented Sep 28, 2019 at 2:51

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
