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
#!/usr/bin/env bash(see stackoverflow.com/questions/10376206/…) ? This line allows my script to be launched directly withfish.#!/usr/bin/env bashis only universal if every system you want to execute the script hasbashinstalled. If you want portability, write your script to be compatible with POSIX standards. Then most shells will be able to execute it without issue (as most common shells are POSIX compliant).#!/bin/shwould be the way to go in my opinion.
