fclean

this is a script i've been using for a while now with great success. what it does is clean up filenames so they are good to go on a linux-system. this means spaces will be replaced by underscores and special characters will be removed. also, the filename will be converted to lowercase. i've been using this mainly to clean up my mp3-files. along with my other scripts, append & firep (for appending text and doing find-and-replace), these are my go-to arsenal for making sure my mp3-filenames are in order.

#!/bin/bash
# obtained from paramthegreat @ Arch forums
# replaces spaces with underscores
# removes unwanted characters
# makes everything lowercase
# replaces hyphen after numbers with underscore

ls | while read -r FILE
do
    mv -v -- "$FILE" `echo $FILE | tr ' ' '_' | tr -d '[{}(),\!]' | tr -d "\'" | tr '[A-Z]' '[a-z]' | sed 's/\([0-9][0-9]\)-/\1_/'`
done
exit 0

you just run this script in a directory and it will clean-up all files in there.

now, the time may come when you are handling an exceptionally large collection of files (mp3s, in my case), all divided in different directories and subdirectories and so on. to make stuff a little bit easier, i have also made this second script, fclean_dir, which will go down 1 level of directories and run fclean there. so, if you have a directory filled with 20 subdirectories, fclean_dir will clean up every file in each of those subdirectories.
of course, when the subdirs have more subdirs, you have to 'cd' a level deeper and run fclean_dir again from there.

#!/bin/bash

traverse() {
   local d startdir
   cd -- "$1" || exit 1 
   if [[ $(find -maxdepth 0 -type d -empty) != "." ]]; then
      for d in *; do
         [ -d "$d" ] && traverse "$d"
         fclean
      done
   fi
   cd .. || exit 1
}

traverse .

edit: changed fclean_dir to just use my traverse-snippet and go multiple dirs deep. just to be clear, you'll also need fclean to have this work.

hope someone has some use for this!

Re: fclean

Do you just save these scripts in ~/bin and then when in the required directory via Terminal execute what ever the filename/command was?

Re: fclean

well, you just save them in a directory that is inside your $PATH variable.

echo $PATH

in my case they're in ~/scripts, but if you'd rather use bin, go ahead. if it is in ~/bin and that is in your path, you can just call the scriptname from where-ever you are on your system and it should work.

oh damn and i always forget this because i have a script that does it for me (@script, probably in my signature too)... but you need to do

chmod +x YOURSCRIPTNAMEHERE

to make it executable.
gotta remember to put that in with every script i post...

Re: fclean

^ Thanks, since 'bin' is there I tend to just use that.

  I would of done that but as you say probably a good idea to put that in.

Re: fclean

^ people gotta just start using my @script, and this problem wouldn't exist. can't really understand why that script hasn't gotten more attention, as it works so fantastically. @script SCRIPTNAME and you have a chmodded script in an open editor.
well, as long as i love it

Re: fclean

^I'm going to use it tonight, so your effort isn't totally in vane.

I have a question though, do you use Dropbox?  As i noticed that when Dropbox is installed the folder created in ~/ is 'Dropbox' and not 'dropbox'.  Would changing the capitalistion of this folder prevent Dropbox from working/syncing?

I shall probably find out later myself anyway.

Re: fclean

thanks kri5, glad you like it! i use it myself all the time. and nice that you're also trying out @script. if you like it and continue to use it, please drop by its thread and leave a message there too.

about the Dropbox-dir: i think changing the name to lowercase will prevent it from working, but am not 100% sure. also be careful with this script around downloads from torrent-files etc, as your torrent-client won't be able to find the files when they're suddenly all lowercase (had that happen myself so speaking from experience here )
