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.
