UNIX for Dummies Questions & Answers

I need to chmod a bunch of files with a specific extension in one directory.

If I understand correctly first I would run ls command like this

ls -R | grep .mp3 > /tmp/list

once I have the output file I should be able to run a loop to chmod all the files in the list created.
This is where I am not sure on how to do this.
Here is what I have tried.

for i in /tmp/list ; chmod 777 "$i"

But i get an error

-bash: syntax error near unexpected token `chmod'

All you need to do is cd into the directory and...

chmod 777 *.mp3

Code:

ls *.mp3 | xargs chmod 777

Thanks, I knew there was a simpler way to do it, but since I am a noob, i just wanted to see what other options I have to learn some new stuff.

Why not just

Code:

chmod 777 *.mp3

?

=> eugenes18t: in you code

Code:

for i in /tmp/list ; chmod 777 "$i"

there are two errors.
And, oh, do you really want to give read+write access to all users? A simple

Code:

chmod u=rwx,g=r,o=r

should be enough?

Just using find will work for a single or more complex directory structure.

Code:

find /directory/path *.mp3 -exec chmod 744 {} \;
