Hello McGaida, and welcome to the Monastery!

A side note: Did you really intend to match the | character?

Within a character class, | is just a character with no special meaning. Also, a hyphen doesn’t need to be backslashed if it’s the first or last character in the class (because Perl is smart enough to know that it doesn’t denote a range in these cases). So, assuming that you did mean to match the | character, your regular expression can be simplified from this:

/^([\w|\s|\/|\-]+)$/
[download]

to this:

/^([\w|\s\/-]+)$/
[download]

or, with different delimiters, to this:

m{^([\w|\s/-]+)$}
[download]

See perlrecharclass#Bracketed-Character-Classes.

Update: Re-ordered for improved clarity, thanks to MidLifeXis.

Hope that helps,
