search and replace ip address ?

cdm33 · 06-29-2007, 10:18 AM

Hello everyone,

Anyone know of a sed script (or any other script) which will find and replace IP addresses in a log text file ?

I've tried this but no substition takes place. I thought sed takes in regex's but this one doesn't seem to work.

sed 's/\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}//g' ip_address.txt > no_ip_address.txt

"s|[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\} ||g" maybe?

I see unSpawn beat me to the punch, I did it with:

Code:

sed 's/[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}.[0-9]\{1,3\}//g' ip_text.txt > no_ip_text.txt

unspawn and bsdunix - that did it. Thanks for you help. The only thing is that it also removed time stamps. I'll have to tweak it a bit.

I would have thought this would have done it also: (\d{1,3}\.){3}\d{1,3}

. . . but that didn't seem to work.

Actually [0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\} does the trick

Thanks for your help - you really helped
