如何检测Bash中的符号链接是否断开? [英] How can I detect whether a symlink is broken in Bash?

问题描述

我运行find并使用[ \( -L $F \) ]遍历结果以收集某些符号链接.

I run find and iterate through the results with [ \( -L $F \) ] to collect certain symbolic links.

我想知道在这种情况下是否有一种简单的方法来确定链接是否断开(指向不存在的文件).

I am wondering if there is an easy way to determine if the link is broken (points to a non-existent file) in this scenario.

这是我的代码:

FILES=`find /target/ | grep -v '\.disabled$' | sort`

for F in $FILES; do
    if [ -L $F ]; then
        DO THINGS
    fi
done

推荐答案

# test if symlink is broken (by seeing if it links to an existing file)
if [ ! -e "$F" ] ; then
    # code if the symlink is broken
fi
