Hello all,
I''ve been fighting a pesky regex issue and I was hoping somebody might
have
a solution handy. I''m trying to evaluate the hostname variable based
on a
few regex entries and apply some configurations accordingly.
Here''s what I''ve got:
if ($hostname == ''/^([a-z]*[-]\d{2,})*$/'') or ($hostname ==
''/^([a-zA-Z0-9])*$/'') {
another variant:
if ($hostname == ''/^([a-z]*[-]\d{2,})*$/'') || ($hostname ==
''/^([a-zA-Z0-9])*$/'') {
I expect the second option to work as it seems - according to my reading -
to be more "ruby friendly".
Has anybody used this syntax successfully in the past? Additionally, I
suspect I could be bastardizing this as I''m not familiar with ruby.
Thanks in advance for the help.
Cheers,
Mike

Thank you very much Peter. I also found that putting the regex entry in single quotes - as in my above examples - does not give me the expected results. As per your example, the regex entries are properly parsed when entries start and end with a forward slash. I hope this helps somebody else down the line. Cheers and thanks again.
