Question

I have a text file , that I want to find some codes in it , each code consist a number of 3 digits + 7 capital letters
examples : 374ANSKJDS ; 3UKRHDPO ; 99RWLFOPE
my question how find these code by numeric range using grep or sed ?
for example I want to find codes starting from 750 to 900 ?

thanks

EDIT

now that i did it using grep thanks to all , can somebody give the command to do it using awk under windows ?

Answer 1

You can not compare the value of numbers using regexes. However, you can kind of work around this issue by specifying multiple patterns. For the interval you specified (750-900), you could use the following regex:

(7[5-9][0-9]|8[0-9][0-9]|900)[A-Z]{7}
