chopping up directories with sed:

trscookie · 02-28-2008, 02:55 PM

Hello all,

I have quite a few music files that I want to move from Win$lows to *nix but they have all been recorded in wma format.

I know how to convert the files from wma to mp3 however because there are quite a lot of files I would like to recursively convert the files, to do this though I will need to list all of the wma's and the directory they are in:

Code:

find . -iname *wma | sed -e 's/\/*\/*.wma//g'`

The command above kind of works but it prints the OP like this:

Code:

./music/Frank Sinatra/20 Classic Tracks/01 Come Fly With Me
./music/Frank Sinatra/20 Classic Tracks/18 Cheek to Cheek
./music/Frank Sinatra/20 Classic Tracks/04 Moonlight in Vermont
./music/Frank Sinatra/20 Classic Tracks/11 Come Dance With Me
./music/Frank Sinatra/20 Classic Tracks/13 Just in Time
./music/Frank Sinatra/20 Classic Tracks/05 Autumn in New York
./music/Frank Sinatra/20 Classic Tracks/09 London by Night
./music/Frank Sinatra/20 Classic Tracks/03 French Foreign Legion
./music/Frank Sinatra/20 Classic Tracks/19 Baubles, Bangles and Beads
./music/Frank Sinatra/20 Classic Tracks/12 Something's Gotta Give
./music/Frank Sinatra/20 Classic Tracks/15 Too Close for Comfort
./music/Frank Sinatra/20 Classic Tracks/16 I Could Have Danced All Night
./music/Frank Sinatra/20 Classic Tracks/14 Dancing in the Dark
./music/Frank Sinatra/20 Classic Tracks/08 Brazil
./music/Frank Sinatra/20 Classic Tracks/02 Around the World
./music/Frank Sinatra/20 Classic Tracks/06 Let's Get Away from It All
./music/Frank Sinatra/20 Classic Tracks/10 It's Nice to Go Trav'ling
./music/Frank Sinatra/20 Classic Tracks/20 Day In - Day Out
./music/Frank Sinatra/20 Classic Tracks/17 Saturday Night (Is the Loneliest Night of the Week)
./music/Frank Sinatra/20 Classic Tracks/07 April in Paris

I would like it to chop the whole filename off and just leave the dir that the files are in.

Thanks, trscookie.

Code:

man basename

and

Code:

man dirname

Hi,

If you do need to use sed:

Pipe the find command to sed 's%.*/$.*$%\1%'

Hope this helps.

Or use bash internal string fiddling:

Code:

find . -iname *wma | sed -e 's/\/*\/*.wma//g'` | while read line ; do
  dir="${line%/*}"
  echo "$dir"
done | uniq

Or GNU find using -printf:

Code:

find . -iname *wma -printf '%h\n'

Note that the above is not portable, although this is:

Code:

find . iname *wma -exec dirname '{}' ';'

Thanks, trscookie.

if you are using GNU find

Code:

find . -iname "*.wma" -printf "%f\n"

Code:

find . -iname "*.wma" | while read -r f
do
 echo ${f%/*}
done

wow thank you all for the replies, I am just about to go on a converting rampage!!! trscookie.

Hope you realize that you can still run .wma on Linux.

trscookie · 02-29-2008, 03:22 AM

yea I know you can run them, but it doesnt allow you to burn them to disk and doesnt like you moving them to your Ipod either, they are just a PITA.
