CHMOD now perms for nothing

duryodhan · 10-16-2006, 09:53 PM

I was workin as root for so many days and as everyone told me not to use root I decide d to make a new user. But I couldn't play my mp3s as permission denied.

So i went into the dir and did
chmod a=rw -R *

now it turns out I have access to nothin even ls gives permission denied even though I am on su. Apart from reinstalling slackware what else can I do?

You took out execute permissions from files. You can change the permission by mounting the partition with your Slackware CD, but it will take you a lot to restore the permissions manually. Search in this forum, i remember seeing a nice script to restore the permissions using MANIFEST from CD.

Edit: Here's one script to do it: http://homepages.paradise.net.nz/~cameronk/progs.html

Well to do it manually, go back to the folders that you messed up lol

Code:

chmod -R 0755 folder
chown -R root:users folder

This makes all the files and folders accessible.
The second adds ownership for the users group so that any other users can view/play only.
Now if you're like me and hate seeing green .mp3s do this

Code:

find ./ -name '*.mp3' -exec chmod -x {} \; 2>/dev/null

hey Mr-C,
Your reply was a little late, I reinstalled Slackware before your reply. But tell me how would chmod work if I have removed all executable permissions?
BTW, I messed up the new installed too. http://www.linuxquestions.org/questi...28#post2467228
I guess I will have to format and reinstall.

find ./ -name '*.mp3' -exec chmod -x {} \; 2>/dev/null

The syntax seems fine, it should work. Try removing the 2>/dev/null part (keep the ; sign, it's important there), it sends the error messages to /dev/null and maybe you are missing something

You need to escape the {} characters with either a backslash or singlequotes. I personally prefer single quotes.

Code:

find . -name '*.mp3' -exec chmod -x '{}' \;

Thats peculiar; It works for me....did you try the single quotes as suggested?
