IP address leading zero padding for sorting

[sdunne]

I've been searching the forums for the last 15 minutes without sucess so I've decided to post a plea for help.

I need to zero pad ip addresses within a flat text file so I can then sort them correctly. ie 1.20.30.254 becomes 001.020.030.254

Can some kind soul post up a regular expression that will work with Textpad search/replace that to do this ??

You can't do it in one step in TextPad. Here's a way to do it in two steps:

Find what: \<([0-9])\>
Replace with: 00\1

[X] Regular expression

Replace All

Find what: \<([0-9]{2})\>
Replace with: 0\1

[X] Regular expression

Replace All

These assume you are using Posix regular expression syntax:

Configure | Preferences | Editor

[X] Use POSIX regular expression syntax

Thanks Ben, that's enough to get me started!
