Finding number ranges using grep

Is it possible for me to find numbers in a file by a range using grep?

cat data | cut -f1 | grep <info>

Im trying to find information and extract every amount that is less than a number (ie less than 75 or whatever)

Is this possible?

Hey There,

I don't believe it's possible in grep, but you can do it pretty simply using egrep - with your example:

cat data|cut -f1|egrep '[0-9]|[1-7][0-5]'

I may be wrong about whether egrep counts from 0 up or up to 0, but the concept is the same.

Hope that helps Smilie

, Mike
