hey i created a script to pull specific ip ranges from the log file. my problem is that it doesn't pull what i am telling it to. right now it goes something like this.

egrep '10.7.[144-167]' txt file

it pulls any lines that start with a 1, 4, 6, or 7. what i want it to do is pull any ips in the range of 144-167, but nothing i have tried works, any ideas?

thanks in advance.

First off - the '.' doesn't match '.' - it matches any character. To get it to match '.' you need a backslash escape.
Second - the range brackets only work on a single character, not on values as you have them above.

Try:

Code:

egrep '10\.7\.1(4[4-9]|5[0-9]|6[0-7])'

yeah i had done the backslash to comment out the "."s because they are just place holders in the script essentially, but i haven't tried separating the ranges.

Thanks for the idea i'm going to give it a go now.

 

hey broom, the syntax you posted worked in my testing, but i couldn't to working when it was pulling straight from the snort log. needless to say some playing with it later and a sed and awk command we're in business

thanks again.

 

Glad you got it going!

Harry.
