I could be wrong but I don't think \w will not match a hypen "-" so
the test will fail.
This works for me:
if ($_=~/\d{1,2}-(\d{2}|\w{3})-\d+/)
HTH,
Dp.
Opps, yes John that correct. I didn't scroll down to the bit where it said
Output should be.
Thanks for the reply. I added strict and warning, and thankfully,
there were no messages.
The while loop on the file handle makes sense - I should do that.
What are you referring to in the if part? I see I have an unescaped
hyphen which
I will make \- in the regexp compare.
Who escaped a hypen? There is no need to escape a hypen. You escape
meta-characters and a hypen isn't.
But what is the compare you are
writing?
My Regex was incorrect, as John pointed out. I was looking for
1 or 2 digit, a hypen, a 2 digit number of 3 character string, a hypen
and any number of word characters.
You only want two digit day values and a 2-4 digit year value so
/\d{2}-(\d{2}|\w{3}-\d{2,4}/ would be the regex I would use.
Have a look at perldoc perlretut
Also, I ran the script many times just now - it runs so fast, I can't
see why it's
causing the CPU surge:
<Q>$ time proc-js*pl
0.29s real 0.24s user 0.04s system
<Q>$ time proc-js*pl
0.33s real 0.28s user 0.03s system
<Q>$ time proc-js*pl
0.39s real 0.34s user 0.05s system
Can't help with that. :-/
Dp.
