下面是一个最简单的实现,可以解决大多数问题,缺陷是对于软链接显示的是软链接所在的目录
lineos:false
代码如下:
#!/bin/bash
DIR="$( cd "$( dirname "$0" )" && pwd )"

这个版本解决了使用ln -s target linkName创造软链接无法正确取到真实脚本的问题。
lineos:false
代码如下:
#!/bin/bash
SOURCE="$0"
while [ -h "$SOURCE" ]; do # resolve $SOURCE until the file is no longer a symlink
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
SOURCE="$(readlink "$SOURCE")"
[[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE" # if $SOURCE was a relative symlink, we need to resolve it relative to the path where the symlink file was located
done
DIR="$( cd -P "$( dirname "$SOURCE" )" && pwd )"
