remove the part of the string that is after the second to last '/'

[einerwitzen]

I have a string "$var = "one/two/three/four/five/six/";"
(note the last ' / ' on it. I need to be able to remove just the last item, leaving the rest as a string,
"$var2 = "one/two/three/four/five/";

Is there a simple way to do this?

How about



$string =~ s!^(.*/).*?/$!$1!;


Guess I just prefer non-greedy matching to negated character classes.

1. dude, what does mine say?
2. "sweet", what about mine?
3. "dude", what does mine say?
4. GOTO 2

$var =~ s![^/]*/$!!;

Have fun! :-)

Or the non cool way! Regular expression are for weenies! :)

$var = "one/two/three/four/five/six/";
split /\//, $var;
pop;
$var = $var . $_ foreach(@_);

You weenie! You used a regular expression! :)

I think I like this way of avoiding regexes better:

substr($var, rindex($var, '/', length($var) - 2)) = '';

There are lots of ways to do it, and this thread will likely fill up with them. I can't help noticing that what you're looking for resembles the unix command "dirname", however.

chomp($str = `dirname $str`);

Yes, it's silly and not portable. I'm just covering a base here. :-)

The dirname method in File::Basename would be a good choice if you are in fact manipulating directory paths. This module is reasonably platform independent and part of the core Perl distribution.

use File::Basename;

my $dir = dirname($filename);

Do "perldoc File::Basename" for more information.

#If you don't need the original string:
$var =~ s|[^/]+/$||;

#If you would like to leave $var unchanged:
($newVar) = $var=~ m|(.+/)[^/]+/$|;
