Unix Tip #4068- April 1, 2012
LINKS THAT POINT TO NOTHING
find / -type l -print |perl -nle '-e || print';
This will look for all links
that are dead and print it
out. It can be piped to a file
and unlink it later. It is wise
to list the links first and save
the output to a file. This is in
case if the links are needed by
users which remove those files
temporary for testing or
housekeeping.
