Shell Programming and Scripting

Hi:

I have a collection of mp3s and I need to create 1 xml file per mp3.

I have:

recording1.mp3
recording2.mp3
etc

and I want to generate this kind of files.

recording1.xml
recording2.xml

and inside each xml file I need to add a url prefix and then the filename at the end.

So if my url is www.servername.com/mp3s

i need to have inside the xml something like

<file>www.servername.com/mp3s/recording1.mp3</file>

for the second file
<file>www.servername.com/mp3s/recording2.mp3</file>

Like that.

I have run into some issues so I would like to know from you guys.

Thanks in advance.

ps. if it works in subfolders too then you are my shell god.

You may try something like this (assuming unique filenames with no embedded newlines, I also assume that you want to store all xml files in the current directory):

Code:

_url="http://www.servername.com/mp3s" export _url

find . -name '*.mp3' |
  while IFS= read -r; do
    _f="${REPLY#*/}" _p="${_f##*/}"
    printf '<file>%s/%s</file>\n' "$_url" "$_f" > "${_p%.*}.xml"
done

Thanks!

just one more thing.

How should I change it so that the xml is generated next to the mp3?

so if i have

folder1/audio1.mp3
folder1/2001/recording.mp3

i get

folder1/audio1.xml
folder1/2001/recording.xml

I dont want to have all xml files on the same dir since the mp3s will be moved and I will leave the xml files as fake mp3s that link to the mp3s on the other server.

This should work:

Code:

_url="http://www.servername.com/mp3s" export _url

find . -name '*.mp3' |
  while IFS= read -r; do
    _f="${REPLY#*/}"
    printf '<file>%s/%s</file>\n' "$_url" "$_f" > "${_f%.*}.xml"
done

perfect. a million thanks.
