$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) 

使用bash >= 3，以下工作:

$ ./s
0 is: ./s
BASH_SOURCE is: ./s
$ . ./s
0 is: bash
BASH_SOURCE is: ./s

$ cat s
#!/bin/bash

printf '$0 is: %s\n$BASH_SOURCE is: %s\n' "$0" "$BASH_SOURCE"

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)。

我发现这一行总是有效的，无论文件是源文件还是作为脚本运行。

echo "${BASH_SOURCE[${#BASH_SOURCE[@]} - 1]}"

如果你想遵循符号链接，在上面得到的路径上使用readlink，递归或非递归。

单行程序工作的原因可以通过使用BASH_SOURCE环境变量及其关联的FUNCNAME来解释。

BASH_SOURCE An array variable whose members are the source filenames where the corresponding shell function names in the FUNCNAME array variable are defined. The shell function ${FUNCNAME[$i]} is defined in the file ${BASH_SOURCE[$i]} and called from ${BASH_SOURCE[$i+1]}. FUNCNAME An array variable containing the names of all shell functions currently in the execution call stack. The element with index 0 is the name of any currently-executing shell function. The bottom-most element (the one with the highest index) is "main". This variable exists only when a shell function is executing. Assignments to FUNCNAME have no effect and return an error status. If FUNCNAME is unset, it loses its special properties, even if it is subsequently reset. This variable can be used with BASH_LINENO and BASH_SOURCE. Each element of FUNCNAME has corresponding elements in BASH_LINENO and BASH_SOURCE to describe the call stack. For instance, ${FUNCNAME[$i]} was called from the file ${BASH_SOURCE[$i+1]} at line number ${BASH_LINENO[$i]}. The caller builtin displays the current call stack using this information.

您可以使用$0来确定您的脚本名称(带完整路径)-要获得只有您可以使用该变量的脚本名称

basename $0

如果你调用shell脚本喜欢

/home/mike/runme.sh

$0是全名

 /home/mike/runme.sh

Basename $0将获得基本文件名

 runme.sh

你需要把这个基本的名字放到一个变量里，比如

filename=$(basename $0)

并添加额外的文本

echo "You are running $filename"

你的脚本就像

/home/mike/runme.sh
#!/bin/bash 
filename=$(basename $0)
echo "You are running $filename"
