partitions permission query

[oaridus]

Hi, I am trying to save a document in a mounted partition but its says I don't have the permissions to save the file. It says this for any partition. I am only able to save it in my home directory. How to I solve this. Basically I am trying to access a file in linux in windows xp. So I need to save the file in fat 32 partition which it is not allowing me to do. Please help

You can specify the owner and group for a vfat partition automounted at boot in /etc/fstab.

Code: Select all

/dev/sdXX                   /mnt/<mountpoint>                    vfat            auto,rw,quiet,umask=000,shortname=lower,uid=1000,gid=1000   0      0

Substitute sdXX for the actual partition and /mnt/<mountpoint> for the actual mountpoint. Your actual uid and gid can be found by running in a terminal

Code: Select all

id

Edit fstab as root then remount or reboot and your partition will be writable as the user specified by the uid.

My fstab file looks like the following

-------------------------------------------------------------------------------
<file system> <mount point> <type> <options> <dump> <pass>

proc /proc proc defaults 0 0

/dev/sda5 / ext3 errors=remount-ro 0 1

/dev/sda7 /data ext3 defaults 0 2

/dev/sda9 /win_small vfat defaults 0 0

/dev/sda10 /win_big vfat defaults 0 0

/dev/sda6 none swap sw 0 0

/dev/hda /media/cdrom0 udf,iso9660 user,noauto 0 0

----------------------------------------------------------------------------------

I typed "id" in the terminal and got three different ids for three different users

root - 0
sid - 1000
bunty - 1001

I want to write and save to files in the fat partition using any of these users. Is it possible?? Also the "0" in the fstab file --- do they mean the permission for only root?? please clarify

Code: Select all

man fstab

Code: Select all

man mount

It's all right there. Think of it as an entry level test.

The answers you seek are indeed in the man pages RollingStone posted.
I'll give you a little more help. If you need rw access for more than one user, the options users and rw will be useful instead of defaults.
