$string=\\Server\user;

Syntax error. Add quotes (And note that \\ will evaluate to a single backslash).

@tmp=split(/\/,$string);

Syntax error. The backslash escapes the delimiter, leaving an undelimited string.

Does anybody have any suggestions?

$string ="\\Server\user";  #WRONG!

2) What does @tmp look like? Try Data::Dumper. Is $string being placed in element 0, or what?

$string ='\\Server\user'; #right

Even with single quotes, backslash can escape delimiters and itself. $string be \Server\user.

$s = '\\Server\user\dir';
@tmp = split /\\+/, $s;
print join(" -- ", @tmp);

You're going to want to put a double backslash in to match a single, and you might want to add the '+' after it to match multiples inline.

--
$you = new YOU;
honk() if $you->love(perl)

# example 1
@tmp = split /\\/, substr($string, 2);
print join(',', @tmp), "\n";

# example 2
$string =~ s/^\\+//;
@tmp = split /\\/, $string;
print join(',', @tmp), "\n";

# example 3
@tmp = split /\\+/, $string;
shift @tmp;
print join(',', @tmp), "\n";

I always run to modules when I have regexp problems:

#!/usr/bin/perl -w
use strict;
use File::Basename;

my $fullpath = '\\Server\dir\user';
my $popped;
my @fileparts;

while($fullpath ne "" && ($popped = basename($fullpath)) ) {
    push @fileparts, $popped;
    $fullpath = dirname($fullpath);
}
for(@fileparts) {print "$_\n"}

Thanks for all the leads.
TYPO - I did escape the backslashes, posted wrong sorry
