How do I split a string containing path+filename

psmail has asked for the wisdom of the Perl Monks concerning the following question: ⭐ (strings)

I need to separate the filename and path from a string. e.g.

$a = "/root/subroot/subsubroot/filename";

I want to separate filename and the path.
i.e. The output should be
$b = "/root/subroot/subsubroot/"
$c = "filename"

Thanks

For maximum portability, use File::Basename, a standard CPAN module: `use File::Basename; use strict; # get full path in $path my $filename = basename($path);` [download]	[reply] [d/l]

The complement to `basename` that arturo forgot to mention is `dirname`, so your code would look like this: `$a = "/root/subroot/subsubroot/filename"; $b = dirname $a; $c = basename $a;` [download] That said, do not get into the habit of using variables `$a` and `$b`. You are much better off giving them descriptive names, which will help your code self-document itself. A better way of writing your code would be `my $filespec = "/root/subroot/subsubroot/filename"; my $path = dirname $filespec; my $filename = basename $filespec;` [download]	[reply] [d/l] [select]

File::Spec. See my review.	[reply]

Quick and dirty regex answer (for Unix or DOS): `($b,$c) = $a =~ m\|^(.*[/\\])([^/\\]+?)$\|;` [download] I agree with grinder that your var names are obfu, which has its place, but usually we choose descriptive names like $p and $f or even $pathname and $filename ;-)	[reply] [d/l]
