Rename 100+ files from a text file

AGazzaz · 09-25-2008, 04:25 PM

Hello,
I have a folder with 114 files, these files are numbered 001, 002,...
I want to rename these files to names found in a text file
How can I do that?!

Thanks.

What's the format of the text file - how about some example lines?

I have no idea if this works lol...

#!/bin/bash
comm oldname newname > both
for f in both; do
first=`cat both | 'awk {print$1}'`
second=`cat both | 'awk {print$2}'`
mv $second $first
done

Thank you for your replies,

The files extention is mp3 and the text file format is txt

I would like to change the files as follow:
001.mp3 ---> Wonders.mp3
002.mp3 ---> Magic.mp3
003.mp3 ---> lame.mp3

now the names; "wonders","magic","lame" are found in a text file

how can I rename the long list of files?

Sample lines?

AGazzaz · 09-25-2008, 06:15 PM

The file will look like this:

Wonders
Magic
Lame

I hope it helps.

I'm sure you could do it more elegantly wit hawhk or some thing, btu try creating a script file like

Code:

#!/bin/sh -x
#

echo "" > outfile

a=0
while read song
do a=$(($a+1));
if [ $a -le 9 ]; then
  echo "mv 00"$a".mp3" $song".mp3" >> outfile
else if [ $a -le 99 ]; then
       echo "mv 0"$a".mp3" $song".mp3" >> outfile
     else echo "mv "$a".mp3" $song".mp3" >> outfile
     fi
fi
done < "myfile"
chmod u+x outfile
./outfile

This will take a list of names like you gave above in myfile and rename via an intermediate script (outfile).

This could be far better. At the moment, I'm assuming that the number of files is the same as the number of names and also that the order of items in your text file correctly matches the order of mp3 files. Both are bad assumptions. But this may give some ideas for you or others to improve:

Code:

#!/usr/bin/perl
use strict;
use warnings;

my @names;
my @files = <*.mp3>;

while( <> )
{
  push @names, $_;
}

chomp( @names );

my $i = 0;

while( $i < scalar @names )
{
  my $title = $names[$i] . '.mp3';
  rename $files[$i], $title;
  $i++;
}

When you run it, give the name of the text file as a command line argument, eg. if you call the script "fix", do perl fix textfile

if you have Python

Code:

#!/usr/bin/env python
import os,glob
FILES=glob.glob("[0-9]*.mp3")
data=open("file").readlines()
data=[i.strip() for i in data]
for n,files in enumerate(sorted(FILES)):
    print "rename %s to %s.mp3 "%( files, data[n])
    os.rename(files,data[n]+".mp3")

#!/bin/bash

[ $# -lt 2 ] && { echo "Usage: script mp3dir namelist"; exit; }

for f in $1/*; do
((n++))
name=$(sed -n "${n}p" $2)
mv $f ${f/[0-9]*./${name}.}
done
