How do I Change directory permissions?

Stevetgn · 06-08-2004, 03:32 AM

Sorry guys and gals I've asked this before, forgotten the answer and can't find it in the forum again!

I have a directory on a Windows FAT32 partition where I keep all my music files.
I want to use this directory in both windows and linux and have full r w permissions for the directory (and all its sub directories!) I think the old chmod is involved somewhere but I can't remember!?!?

Thanks in advance for your help

Steve

PS - I'm fed up with being a Linux newbie. Is there one definitive place I can learn all the chmod, grep, -r -a command, command command, etc, etc, etc!!!!

to change dir-permissions (-R = recursive) use:

chmod -R permissions /dirname

example:
chmod -R 777 /dirname
or
chmod -R u+rw /dirname

not to mention,

the mountpoint must be set correctly in /etc/fstab:

for example:
/dev/hdc /windowsshare vfat uid=500,gid=500, rw 0 0

--> read/write permissions for user (uid=500) on share !

Quick reply, thanks my friend.

Do you see what I mean though? where or how do you learn about all the advice you've just given me???

Sorry for my ignorence: does the "-R" change all sub directoies then and should it be an upper or lower case R(r)?

"-R" change all subs and it should be in uppercase!

unlike many other switches which are in lower case, the recursive-switch of CHOWN and CHMOD is in upper case.

learning and experiencing linux and especially the different distris is a very hard and nightly work! :-(

I found this site very helpful for doing CLI stuff:

You can't use chmod to set permissions for a FAT partition. As overlord indicated, the key to having full read/write access (for ordinary users) is in the mounting options. If you automatically mount the partition with a /etc/fstab entry, it should look like the following:

Code:

/dev/hda4    /w98          vfat     umask=0000,users     0   0

Of course, you'll need to use your own partition and mount point. The key elements here are the 'umask=0000, users' options.

To answer your second question, the single best source of information that I've found is the Rute User's Tutorial and Exposition.

Enjoy!
