查找断开的符号链接

今天看 man find 的时候发现了一个 xtype 选项。 

-xtype c
       The same as -type unless the file is a symbolic link.  For symbolic links: if the -H or -P option was specified, true if the file is a  link
       to  a  file of type c; if the -L option has been given, true if c is `l'.  In other words, for symbolic links, -xtype checks the type of the
       file that -type does not check.

也就是说，可以通过 -xtype l 来搜索断开的符号链接,像下面这样 

export TMPDIR=/tmp/test
ln -s $(mktemp --dry-run) $(mktemp --dry-run)
find ${TMPDIR} -xtype l

/tmp/test/tmp.I6YuQ7Y7he
