这对./self.sh， ~/self.sh, source self.sh, source ~/self.sh很有效:

#!/usr/bin/env bash

self=$(readlink -f "${BASH_SOURCE[0]}")
basename=$(basename "$self")

echo "$self"
echo "$basename"

演职员:我综合了多个答案才得到这个答案。

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!

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

回显“您正在运行$0”

$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) 

在所有情况下获取脚本或源脚本的“真实路径”:

fullname=$(readlink $0)  # Take care of  symbolic links
dirname=${fullname%/*}       # Get (most of the time) the dirname
realpath=$(dirname $BASH_SOURCE) # TO handle sourced scripts
[ "$realpath" = '.' ] && realpath=${dirname:-.}

下面是要生成的bash脚本(在新创建的“workdir”子目录中，在当前目录的“mytest”中)，该bash脚本将派生另一个脚本，该脚本将调用bash定义的函数....测试了许多方法来启动它们:

#!/bin/bash

ret=0

fullname=$(readlink $0)  # Take care of  symbolic links
dirname=${fullname%/*}       # Get (most of the time) the dirname
realpath=$(dirname $BASH_SOURCE) # TO handle sourced scripts
[ "$realpath" = '.' ] && realpath=${dirname:-.}

fullname_withoutextension=${fullname%.*}

mkdir -p workdir
cat <<'EOD' > workdir/_script_.sh
#!/bin/bash

ret=0

fullname=$(readlink $0)  # Take care of  symbolic links
dirname=${fullname%/*}       # Get (most of the time) the dirname
realpath=$(dirname $BASH_SOURCE) # TO handle sourced scripts
[ "$realpath" = '.' ] && realpath=${dirname:-.}

fullname_withoutextension=${fullname%.*}
