Question about batch file processing

I guess a mod can merge it later.

ls -1 *.mp3 | sed "s/\(.*\)\.mp3/\1.mp3 \1_128.mp3/" |xargs -n 2 lame -h

^^works very well on files with names such as: mysong.mp3 or my-song.mp3
my problem is the spaces in between instead of a symbol for e.g. 1 - my fav song.mp3
Can someone please tell me whatelse needs to be added to to the command so that it reads the files with spaces and writes them back in the same format.
example:1 - my fav song_128.mp3

Hey There,

Depending on your xargs, you can use either the -i or -I flag. For instance

xargs -n 2 lame -h

becomes

xargs -I var -n 2 lame -h "var"

so you can quote those filenames with spaces

Cheers,

Mike

That command is utterly complex and cryptic for my tastest. I don't like to use the output of ls for these things, it can only create problems. Besides that, there's no need to use xargs (and it can potentially create problems if the file list is long enough).

In bash I would do:

for i in *.[Mm][pP]3; do j=${i// /_}; mv "$i" "$j"; lame -h "$j"; done

If you use any other shell you still need to use sed. But this will work regardless of the number of files, and don't needs ls or xargs for anything.

thx bro that went easy and smooth and it took care of the space issue in the filenames ;]

[5pyd3r]

is it possible to run the command in pwd and have it read and write recurisvely properly?

Hey There,

I think you can just do this (easiest to type, maybe not the most efficient way)

for i in `find . -name "*.[Mm][pP]3"`; do j=${i// /_}; mv "$i" "$j"; lame -h "$j"; done
