Complex file renaming

Imyrryr · 04-28-2005, 09:09 PM

I have spent quite a bit of time trying to understand how to do this but I have to admit I am a scripting newbie. I have read about sed, tr, rename and gawk. I'm a bit overwhelmed with all the info. This is what I am trying to accomplish. I have a list of files:

background_jpg_jpg.jpg
background01_jpg_jpg.jpg
backdrop_jpg_jpg.jpg
scenery_jpg_jpg_jpg.jpg

The end result that I am trying to get to is this:

background.jpg
background01.jpg
backdrop.jpg
scenery.jpg

The information that I have found 'Googling' is about renaming extensions or putting files in sequence or is very convoluted. Any constructive help is greatly appreciated, not to mention I write stuff like this down in my "Cheatsheet Notebook" for future reference.

EDIT: Did I mention that it's about 400 files?

Here's an example

Code:

#!/bin/bash

dir="/home/images"

for i in `ls $dir` ; do
   j=`echo "$i" | awk -F"_" '{print$1}'`
   mv "$dir/$i" "$dir/$j.jpg"
done

Code:

for file in *_jpg*; do newname=`echo $file | perl -pe 's/_jpg//g'`; mv $file $newname; done

Sed could be used, but I'm more familiar with perl.

Thank you so much for this info, I would of never figured that out on my own, at least not in a timely manner. I think it's time I stop procrastinating and start reading on the ABS book.

You guys rock!
