为了回答Chris Conway的问题，在Linux上(至少)你会这样做:

echo $(basename $(readlink -nf $0))

Readlink输出符号链接的值。如果不是符号链接，则打印文件名。-n告诉它不打印换行符。-f告诉它完全跟随链接(如果一个符号链接是到另一个链接的链接，它也会解析那个链接)。

由于一些注释询问没有扩展名的文件名，这里有一个示例如何完成:

FileName=${0##*/}
FileNameWithoutExtension=${FileName%.*}

享受吧!

简短，清晰，简单，在my_script.sh中

#!/bin/bash

running_file_name=$(basename "$0")

echo "You are running '$running_file_name' file."

把:

./my_script.sh
You are running 'my_script.sh' file.

像这样的东西?

export LC_ALL=en_US.UTF-8
#!/bin/bash
#!/bin/sh

以下是我从Dimitre Radoulov的回答中得到的灵感(顺便说一下，我给他的回答投了赞)。

script="$BASH_SOURCE"
[ -z "$BASH_SOURCE" ] && script="$0"

echo "Called $script with $# argument(s)"

不管你如何调用你的脚本

. path/to/script.sh

or

./path/to/script.sh

$BASH_SOURCE在获取脚本时给出正确答案。

然而，这包括路径，所以只获得脚本文件名，使用:

$(basename $BASH_SOURCE)
