[SOLVED] I have a specific linux bash question about variables and possible hexadecimals.

So I have season one of bleach and it is separated into 5 disks. I have xbmc and I wanted to take a library and add all of my episode from one directory into one file called videodb.xml Which is with in xbmc_videodb_2011-10-08 which is within my bleach folder in my home folder. I found the file names requires different id's for each video I have. Before we go any farther I encoded them into the avi format which I researched to be compliant with the xbox 360.

I put some notes in the shell script.

Code:

#!/bin/bash

echo "<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>" >> xbmc_videodb_2011-10-08/videodb.xml
echo "<videodb>" >> xbmc_videodb_2011-10-08/videodb.xml

a=xx00000000 # This is the starting address
for i in ./*
{
    a++ # I don't know how to make this count up from the starting
######### address so that it does this xx00000000 to xx0000001 and
######### so on.
    echo "    <movie>" >> xbmc_videodb_2011-10-08/videodb.xml
    echo "        <title>$i</title>" >> xbmc_videodb_2011-10-08/videodb.xml

This counts up in hexadecimal.

Code:

a=xx00000000
for i in ./*; do
  atmp=${a/x/0}  # Change first 'x' to '0'
  a=$(printf 'xx%08X' $((++atmp)) )
#        use 'xx%08x' for lower case A-F
  echo $a
done

xx00000001
xx00000002
xx00000003
xx00000004
xx00000005
xx00000006
xx00000007
xx00000008
xx00000009
xx0000000A
xx0000000B
xx0000000C
xx0000000D
xx0000000E
xx0000000F
xx00000010

I did not respond for a while, but yes it worked.

May I also suggest you look up here documents instead of so many echo lines.
