小技巧:查找损坏的符号链接

阅读find命令的手册,在描述“-type l”的章节里发现了这样一段话

symbolic link; this is never true if the -L option or the -follow option is in effect, unless the symbolic link is broken. If you want to search for symbolic links when -L is in effect, use -xtype.

这段话说明,当“-L”打开后只有当符号链接损坏时“-type l”才会返回真。我们可以利用这个特性来寻找损坏的符号链接。例如:

find -L . -type l # 查找所有损坏的符号链接
find -L . -type l -exec rm -rf {} \; # 删除损坏的符号链接
