Permissions Problem

[JJCOOLX420]

Im a complete linux newb but Ive had Linux on my PS3 ever since it went public but i just recently found out about the Yum fixes buy editing the 3 files in the yum repos folder; the problem is when ever i goto try and edit these file i get denied because i dont have the right permissions. Ive also read on the boards where if i go into terminal and type SU then my password i can get thoses permissions, but that method still doesnt work for me. Am i doing something wrong?

are you entering the same password that you used when you installed YDL?

[JJCOOLX420]

im almost 100% sure its the same password

Type su... for superuser to be sure you are root.

It will ask you for the password and you can enter it.

To change permissions useful command is:

chmod 777 filename ... read write for everyone

this is what happens when ever i use chmod 777:
im sure im doing something wrong but the file name is correct and the file is deffintly there?


[JJCOOLX@localhost ~]$ su
Password:
[root@localhost JJCOOLX]# chmod 777 yellowdog-base.repo
chmod: cannot access `yellowdog-base.repo': No such file or directory

Are you sure the file you need to edit is in your home directory? Because that's where that command is being executed.

Try editing

/etc/yum.repos.d

instead

No its in the icon called "Computer" the only thing i have in the home directory is Templates and my background picture

the complete directory for the files are:
Computer/Filesystem/ect/yum.repos.d/yellowdog-base.repo
Computer/Filesystem/ect/yum.repos.d/yellowdog-extras.repo
Computer/Filesystem/ect/yum.repos.d/yellowdog-updates.repo

okay, see this prompt

[root@localhost JJCOOLX]#

that tells me you're root, which is good if you're wanting to edit a configuration file. but it also tells me it's in your "user" home directory.

Now your graphical file manager is abrstracting the file system for you, which is why it's saying:

Computer/Filesystem/ect/yum.repos.d/yellowdog-base.repo
Computer/Filesystem/ect/yum.repos.d/yellowdog-extras.repo
Computer/Filesystem/ect/yum.repos.d/yellowdog-updates.repo

When those files are really in the directory /etc/yum.repos.d

you see Linux commands only do what you tell them to do, tell them to edit a file that's not in the directory you're in without using the full path and you'll get

No such file or directory

So you either need to use fhe full path, or be in the directory with the files.

for example if I wanted to edit those files I would login as root

and then:

cd /etc/yum.repos.d

then an

ls

would list the flies

which should look like this:

yellowdog-base.repo
yellowdog-extras.repo
yellowdog-updates.repo

then you can edit them as needed:

nano yellowdog-base.repo

Now there's probably a way to put your graphical filemanager in root mode and then use it to open the files in a graphical editor but don't ask me how to do that. Ah wait, I'll google it, this should work:

open up a term and type in:

su -l

enter root password

type:

nautilus -f

that should get you a nautilus window with root permissions There might even be a menu option for a "super user mode" file manager window

And usually it's faster just to open up a term and edit with nano or vim or something.

And always remember to exit out of root terms and file manager windows when you're done with them. I'd tell you to use sudo instead of direclty using su but I find sudo annoying myself.

Thx that last post did the trick and i could edit the files just fine
