如何在不进行修改的情况下使FreeBSD，OpenBSD和Linux上的bash脚本正常工作? [英] How do I get a bash script working on FreeBSD, OpenBSD and Linux without modifying it?

问题描述

对不起，标题可能有点恼人，但我没有更好的消息.无论如何，我希望bash脚本能够在FreeBSD，OpenBSD和Linux上运行而不进行修改，但是bash在Linux和BSD中不在同一位置.

Sorry, the headline might be a bit irritating, but I didn't know anything better. Anyway, I want a bash script to work on FreeBSD, OpenBSD and Linux without modifying it, but bash isn't located at the same place in Linux and BSD.

因此，如果我写#!/bin/bash，那么它将无法在BSD上运行，因为bash shell位于/usr/local/bin/bash中.有什么解决方案可以使此脚本在两者上同时起作用?

So, if I write #!/bin/bash then it won't work on BSD, because the bash shell is located in /usr/local/bin/bash there. Is there any solution to get this script working on both?

还是我真的需要提供两个具有不同路径的脚本吗??

Or do I really need to ship two scripts with different paths...?

推荐答案

在shebang(#!/usr/bin/env bash)中使用env应该会使脚本操作系统不可知.

Using env in the shebang (#!/usr/bin/env bash) should make the script OS agnostic.
