How to validate windows path

roteme has asked for the wisdom of the Perl Monks concerning the following question:

Hi,

Looking for Perl code using regular expressions to validate windows path.

For example:

my $dir = "c:\";
if ($dir =~ /REGULAR EXPRESSIONS/)
{
    print ("Valid path: $dir");
} else {
    print ("Invalid path: $dir");
}

Thanks.

No regexp needed, simply check if `$dir` exists with the `-e` test. `if -e $dir print "valid path";` etc...	[reply] [d/l] [select]

No, my program get path from the user as parameter and need to check if the path is valid - if yes then create the folder.	[reply]

Define 'valid'. One approach would be to 'try it and see'. Attempt the create, if that succeeds, check to verify the directory exists¹. In this case, 'valid' means being able to be created. If you define what you mean by 'valid', it may help with the responses. Footnotes: 1 - Winding back if it doesn't exist might be fun... Updates: +10 minutes - Update formatting and footnotes, and added a more generic response. --MidLifeXis	[reply]
