in reply to Using File::Find from a function.

From CPAN doc

find

find(\&wanted, @directories); find(\%options, @directories);

find() does a depth-first search over the given @directories in the order they are given. For each file or directory found, it calls the &wanted subroutine.Additionally, for each directory found, it will chdir() into that directory and continue the search, invoking the &wanted function on each file or subdirectory in the directory.

Update:

You can do this way.

my $file='foo'; my directory='a'; + sub check_existance { + if ( -e $_ && $_ eq $file ) { + print "Found file '$_' in directory '$File::Find::dir'\n"; + } + } find( \&check_existance, $directory );

The check_existance function takes no arguments but rather does its work through a collection of variables.

$File::Find::dir is the current directory name,

$_ is the current filename within that directory

$File::Find::name is the complete pathname to the file.

The above variables have all been localized and may be changed without affecting data outside of the check_existance function.

All is well
