this="$(dirname "$(realpath "$BASH_SOURCE")")"

这将解析符号链接(realpath会这样做)，处理空格(双引号会这样做)，并将找到当前脚本名称，即使是在来源(. ./myscript)或被其他脚本调用时($BASH_SOURCE会这样做)。在所有这些之后，最好将其保存在环境变量中以便重用或方便复制到其他地方(this=)…

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!

$0将给出您正在运行的脚本的名称。创建一个脚本文件并添加以下代码

#!/bin/bash
echo "Name of the file is $0"

然后像这样从终端运行

./file_name.sh
