File::Find traverses a directory tree and calls the wanted function for each directory entry found. Inside the wanted function, you can use lstat or stat or one of the -X functions to decide if you want to process that directory entry. Example:

#!/usr/bin/perl use strict; use warnings; use File::Find; find( { wanted => sub { return unless -l $File::Find::name; print "Found a symlink: $File::Find::name\n"; } }, '.' );

File::Find comes with a script named find2perl. You invoke it like find, but instead of traversing directories, it writes perl code for performing the directory traversal using File::Find to STDOUT. The generated code is not pretty, may have some unused parts, but it generally works:

/tmp>find2perl . -type l #! /usr/bin/perl -w eval 'exec /usr/bin/perl -S $0 ${1+"$@"}' if 0; #$running_under_some_shell use strict; use File::Find (); # Set the variable $File::Find::dont_use_nlink if you're using AFS, # since AFS cheats. # for the convenience of &wanted calls, including -eval statements: use vars qw/*name *dir *prune/; *name = *File::Find::name; *dir = *File::Find::dir; *prune = *File::Find::prune; sub wanted; # Traverse desired filesystems File::Find::find({wanted => \&wanted}, '.'); exit; sub wanted { my ($dev,$ino,$mode,$nlink,$uid,$gid); (($dev,$ino,$mode,$nlink,$uid,$gid) = lstat($_)) && -l _ && print("$name\n"); }
