# split a file by keyword

Strangely enough, I didn’t find any built-in tool to split a file by keyword. I made one myself in `awk`. I put it here mostly for myself. But it could also helps someone else. The following code split a file for each line containing the word `UTC`.

`#!/usr/bin/env awk BEGIN{i=0;} /UTC/ { i+=1; FIC=sprintf(“fic.%03d”,i); } {print $0>>FIC}`

In my real world example, I wanted one file per day, each line containing UTC being in the following format:

    Mon Dec  7 10:32:30 UTC 2009

I then finished with the following code:

`#!/usr/bin/env awk BEGIN{i=0;} /UTC/ { date=$1$2$3; if ( date != olddate ) { olddate=date; i+=1; FIC=sprintf(“fic.%03d”,i); } } {print $0>>FIC}`
