Multiple File Rename
Hi All,
I'm trying to rename multiple files in a directory that are named as such:
Iron_Maiden_-_11_-_Juanita.mp3
Iron_Maiden_-_11_-_My_Generation.mp3
Iron_Maiden_-_13_-_Black_Bart_Blues.mp3
Iron_Maiden_-_16_-_Wasted_Years_'99_(Live).mp3
Iron_Maiden_-_15_-_Charlotte_The_Harlot_'88.mp3
Iron_Maiden_-_10_-_Judgement_Day.mp3
Iron_Maiden_-_14_-_Prowler_'88.mp3
What I would like to do is remove up to the Iron_Maiden_-_14_-_ and rename them to start with the track number and then finish with the name as such:
11-Juanita.mp3
11-My_Generation.mp3
I've looked on the web and I'm completely baffled by the all the info out there.
Thanks for the help.
George

Something like the following should do it:
#!/bin/bash
cd directory
for file in `ls -1`
do newfile=`echo $file | awk -F_ '{print $4"-"$6}'`
echo mv $file $newfile
done
In above change "directory" to the actual directory name where your music files are.
What it does is uses the underscore (_) as the delimiter for awk and prints the 4th and 6th and field as split by that delimiter. It puts the literal dash (-) in between those.

It is not really difficult, you just need to known a bit of regular expressions and bash...I hope this motivate you to learn more about.
Code:
for f in Iron_Maiden*.mp3; do
new=$(echo $f | sed -e 's/Iron_Maiden_-_[0-9]*_-_//');
echo mv "${f}" "${new}";
done
Please, note there is a echo in front of the mv command. This is a debug/safe option. run this as is just to see what is the output. If everything looks good, remove the echo command and the files will be renamed.

The applications gwenrename and krename work well with Konqueror and/or Krusader for doing bulk renaming of files.
The light-weight file browser Thunar comes with a nice GUI for doing the same thing, called Bulk Rename.

strange, but the rename command installed in my system does not have this sed-like feature. It is not mentioned in the rename's man page either...Mine comes from util-linux-2.13-0.54.1.fc7, and yours ?

marozsas,
I tried this the way you described and it worked beautifully.
Thank you, and all the others who contribute help so freely.

I also have this very cool "sed feature" of rename which I discovered not so long ago.
/usr/bin/rename is linked to /etc/alternatives/rename which is linked to /usr/bin/prename
prename is part of perl:
perl 5.8.8-11.1 Larry Wall's Practical Extraction and Report
