in reply to traverse directory recursively and search for pattern

I do this like so. ;)

#!/usr/bin/perl use Modern::Perl; use autodie; my ($dir, $match) = @ARGV; die "directory does not exists $dir" unless -d $dir; die "No match" unless $match; open_readdir($dir, \&process); sub process { my ($dir, $file) = @_; if (-T "$dir/$file") { open my $fh, '<', "$dir/$file"; say "$dir/$file: $_" for grep /$match/, $fh->getlines; $fh->close; } } sub open_readdir { (my $dir = shift) =~ s/\/$//; my $code = shift; my $db; opendir $dh, $dir; my @files = grep !/^\./, readdir $dh; for my $file (@files) { if (-d "$dir/$file") { open_readdir("$dir/$file", \&process); } else { &$code($dir, $file); } } closedir($dh); }
