in reply to stuck on regexp

Well, FreeBSD 'adduser' IIRC displays the regexp that the username must conform to, but I am not at my FreeBSD box now so I can't check that, however here is my stab at a regexp you might need:

/^[A-Za-z][-.A-Za-z0-9_]+$/

This will force the first character to be a-z or A-Z and any other character a-z, A-Z, 0-9, -, . or _. It will also force the login name to be at least 2 characters (I'm not sure if this is what you want) and reject a username made up entirely of numbers (as the first character must be a-z or A-Z)

Hope this helps.

    cheers guys.
    how would i apply the maximum/minimum regexp to this expression:  if ($email !~ /.+\@.+\..+/) {   ?

      Use  .{2,10} instead of  .+ (if I did understand your question)
