You can roll your own recursive function to do this:
sub parse_file ($) {
#Do something with the file here.
}
sub traverse (@) {
my @files = @_;
local *DIRH;
#If @files is empty, why bother?
return unless @files;
foreach my $file (@files) {
#Skip unreadable files.
next unless -r $file;
if (-d $file) {
#If it's a directory ...
chomp(my $cwd = system('/bin/pwd')); #save current directory, ..
+.
chdir($file) || next; #change to the new director
+y, ...
opendir(DIRH,$file) || next; #open it...
traverse((readdir(DIRH)); #and recursively parse it.
closedir(DIRH); #Close the directory.
chdir($cwd); #Change directories back to
+ where we were.
} else {
#If it's not a directory, then parse it.
parse_file($file); #This is where the actual
+work is done.
}
}
}
traverse(@ARGV);
