[Linux OT] Regular expresion question

[Jean Sagi]

You example works for the case I give. Thanks.

I didn't understand ".9" in the patterns you gave; what they are used for?

The pattern works with them and without them, I mean the next statement 
works the way I want:

   [chucho at oolnta hist]$ ls | grep -e "^h1[0-9].9" -e "^h2[0-5].9"
   h100904
   h120904
   h130904
   h180904
   h200904
   h240904
   h250904

   [chucho at oolnta hist]$ ls | grep -e "^h1[0-9]" -e "^h2[0-5]"
   h100904
   h120904
   h130904
   h180904
   h200904
   h240904
   h250904


Finally I wonder if there is a more generic way of handling ranges with 
regular expresions, or maybe I'm trying to use the way they are not 
meant to.


Chucho!
