Matching on a string

[kirk124]

Hi
I am reading a text file which contain the following string:

my $string = "\\domca-prn01\DH4-2139-HP4"

I need to verify that the string I am reading in has "\\" follow by either characters or numbers then "\" then either characters or numbers.

I try it as:

if ( $string =~ /\\\\.*\\.*/) { print"match\n"; } But it did not work.

thanks in advance.

I think that should work if you're reading from a text file, but when you assign it to $string you need to escape the backslashes:

my $string = "\\\\domca-prn01\\DH4-2139-HP4";

hope that helps..

Try this:

if ( $string =~ /\\\\\w+\\\w+/) { print"match\n"; }

\\\\ - 2 escaped backslashes

\w+ - then 1 or more "word" charactors (alphanumeric plus some special charactors)

\\ - 1 escaped backslash

\w+ - and again, 1 or more "word" charactors

I highly recommend the book
