如何最好地包含其他脚本? [英] How best to include other scripts?

问题描述

通常包含脚本的方式是使用源"

The way you would normally include a script is with "source"

例如:

main.sh:

#!/bin/bash

source incl.sh

echo "The main script"

incl.sh:

echo "The included script"

执行./main.sh"的输出为:

The output of executing "./main.sh" is:

The included script
The main script

... 现在，如果您尝试从另一个位置执行该 shell 脚本，除非它在您的路径中，否则它无法找到包含.

... Now, if you attempt to execute that shell script from another location, it can't find the include unless it's in your path.

确保您的脚本可以找到包含脚本的好方法是什么，尤其是在脚本需要可移植的情况下?

What's a good way to ensure that your script can find the include script, especially if for instance, the script needs to be portable?

推荐答案

我倾向于让我的脚本都相互关联.这样我就可以使用目录名:

I tend to make my scripts all be relative to one another. That way I can use dirname:

#!/bin/sh

my_dir="$(dirname "$0")"

"$my_dir/other_script.sh"
