find

Synopsis

find (\&wanted, dir1[, dir2 ...])

Works like the Unix find command; traverses the specified directories, looking for files that match the expressions or actions you specify in a subroutine called wanted, which you must define. For example, to print out the names of all executable files, you could define wanted this way:

sub wanted {
    print "$File::Find::name\n" if -x;
}

Provides the following variables:

$File::Find::dir

Current directory name ($_ has the current filename in that directory).

$File::Find::name

Contains $File::Find::dir/$_. You are chdired to $File::Find::dir when find is called.

$File::Find::prune

If true, find does not descend into any directories.

$File::Find::dont_use_nlink

Set this variable if you’re using the Andrew File System (AFS).
