in reply to Parent directory - regex

There are many ways to do this sort of thing. If your path is always known in a string then one simple approach is this
my $path = "/dir1/dir2/dir3/ .. /dirn-1/dirLast//"; my @pathary = split(/\//,$path); my $parentpath = join('/',@pathary[0..$#pathary-1]); # pop @path; # also # my $parentpath = join('/',@pathary); # works print "$path\n$parentpath\n";
An alternative, if the directory your are in is unknown or changes in an unpredictible manner, might be something like this. Note: This is rather inefficient but works.
use Cwd; my $oldpath = getcwd(); print "$oldpath\n"; $path = '/var/tmpdir'; chdir $path; $path = getcwd(); # for info only print "$path\n"; # for info only chdir "../"; $path = getcwd(); print "$path\n";
