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
lang-bash
$SHELLand why we need it?$SHELLcontains your currently running shell, on most Linux systems this will be/bin/bashbut it could be/usr/bin/zshor something else. The advantage of using the$SHELLvariable is that this way the command will be executed using your regular shell settings.EOFdepends on the earlierEOFand is the standard for multiline input in bash-like shells. If you changed the<<EOFto something else theEOFat the end needs to change too. Which shell (and version) are you using?EOFis working, but notEOF &. Just opens a new line. I use GNU bash, version 4.3.48(1)-release (x86_64-pc-linux-gnu). The first option works for me though, just neededbash -cfor having bash builtins.&at the wrong location with the original answer, try the updated answer :)
