help with a 'while read' loop to change the names of files
Hi,
I am new to scripting, so any help on this would be much appreciated.
I am trying to rename a bunch of files, taking the names sequentially from a list read in another file...
# ls oldnames
file_1
file_2
file_3
# cat names
red
yellow
green
I want the files to take on the names red yellow green as they are read line by line from the file "names"
ie
cp oldnames/file_1 newnames/red
cp oldnames/file_2 newnames/yellow
cp oldnames/file_3 newnames/green
etc....
What I have tried (but doesn't work) -
#! /bin/bash
ls . |while read line
do
echo $line
cat names | while read xx
do
cp $line ../newnames/$xx
done
done
This creates new files but only copies the last entry from the ls to each of them
As you can see my scripting skills are not great - any ideas would be much appreciated.

voice_set_playmode
voice_set_playmode(3alleg4) Allegro manual voice_set_playmode(3alleg4)
NAME
voice_set_playmode - Adjusts the loop status of the specified voice. Allegro game programming library.
SYNOPSIS
#include <allegro.h>
void voice_set_playmode(int voice, int playmode);
DESCRIPTION
Adjusts the loop status of the specified voice. This can be done while the voice is playing, so you can start a sample in looped mode (hav-
ing set the loop start and end positions to the appropriate values), and then clear the loop flag when you want to end the sound, which
will cause it to continue past the loop end, play the subsequent part of the sample, and finish in the normal way. The mode parameter is a
bitfield containing the following values:
PLAYMODE_PLAY
Plays the sample a single time. This is the default if you don't set the loop flag.
PLAYMODE_LOOP
Loops repeatedly through the sample, jumping back to the loop start position upon reaching the loop end.
PLAYMODE_FORWARD
Plays the sample from beginning to end. This is the default if you don't set the backward flag.
PLAYMODE_BACKWARD
Reverses the direction of the sample. If you combine this with the loop flag, the sample jumps to the loop end position upon reaching the
loop start (ie. you do not need to reverse the loop start and end values when you play the sample in reverse).
PLAYMODE_BIDIR
When used in combination with the loop flag, causes the sample to change direction each time it reaches one of the loop points, so it
alternates between playing forwards and in reverse.
