Iterate Over Files in Bash

Sometimes you need to whip up a dirty bash script to process through some text. I needed to iterate over my database log files that I wrote about from my last post and then output the result to a new file. I wanted the output files to have a different extension, but I wasn't sure how to get just the filename from bash, fortunately this post helped.

#!/bin/bash

for logfile in *.log
do

fn=${logfile%.*} #cut extension echo making$fn.data...
egrep '\#\ collect|\:\=' $logfile >$fn.data

done
