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

$PWDand$v, in case you have directory names with spaces in them (lamentably common on some systems).array[index]=..., but you are right that in general you should double-quote variables, and there is no harm in doing so in this case.pushd()function, the builtinpushdcommand prints the directory stack. In this case, it will print the stack before it's de-duplicated. Suggested change:pushd() { builtin pushd "$@" >/dev/null ; dedup ; dirs ; }(not tested).
