Hello everyone,
Maybe not entirely related to music, so forgive me for that. I have been
busy with the following problem for sometime now and I can't seem to
figure it out.
I want to batch create symlinks in the main directory, of all the files
in subdirectories. E.g.
$ls
dir1
dir2
dir3
file1.mp3 -> .dir1/file1.mp3
file2.mp3 -> .dir1/file2.mp3
file3.mp3 -> .dir2/file3.mp3
file4.mp3 -> .dir2/file4.mp3
file5.mp3 -> .dir3/file5.mp3
file6.mp3 -> .dir3/file6.mp3
I tried various shell thingies like:
for i in *.mp3; do ln -s --target-directory=../ $i $i; done
in the subdir, or
for i in ./dir1/*.mp3; do ln -s $i $i;done
with various variations, but it seems impossible to do it this way. What
is the right way to go about this? I know very little Python and some
bash scripting. I want to figure the solution out myself, so any
suggestions/hints related to Python/bash are more than welcome.
Cheers,
Hans

this shell script should also do the job:

How about this?
for x in `find . -type f -name '*.mp3' -print`
do
b=`basename $x`
ln -s $x $b
done
Careful about the quotes, some are backquotes.
I didn't test it, it's just off the top of my head.
You might try it with "echo" before the ln command
just to see what it's going to do before you fire
it off for real.

Or something. This automatically takes care of whitespaces and other
hassles i think.

Hallo,

Almost, but you're trying to link a file on itself here ("$i->$i").
Use this instead:
$ for i in ./dir1/*.mp3; do ln -s $i . ;done
or even more general:
$ for i in */* ; do ln -s $i . ; done

In case you didn't recognize the difference to your first try: You can
use a directory as the second argument to ln as well, then it will
create a link with the same name as the basename of the file in the
first argument in that directory. All the backtick and find tricks
suggested in the other answers of this thread are nice, but way
overkill to your problem.
Keep it simple, stupid. ;)

P.S. Almost forgot to thank you. This one works and is short too!

This I don't understand: so what does the
"." stand for?
"." is the current directory.
From the man page of "ln"
SYNOPSIS
ln [OPTION]... TARGET [LINK_NAME]
--> ln [OPTION]... TARGET... DIRECTORY
ln [OPTION]... --target-directory=DIRECTORY TARGET...
[...]
When using the second form with more
than one TARGET, the last argument must be a
directory; create links in DIRECTORY to each TARGET.

Or omit the loop instead:
$ ln -s */* .
That must be the shortest one, it's as short as
$ cp -s */* .
