View Full Version : [ubuntu] [SOLVED] umask, dmask, and fmask - What do the values mean?

July 28th, 2008, 04:18 AM
I've been learning how to use fstab in Ubuntu and I was wondering what the values for umask, dmask, and fmask mean . I know they have something to do with permissions for FAT32, but I couldn't find anything specifically explaining the syntax. Such as what umask=000 or fmask=027 means. I've tried looking through the Ubuntu documentation page on fstab (https://help.ubuntu.com/community/Fstab) and the Linux Man Pages (http://linux.die.net/man/8/mount) to no avail.

Also, does each *mask deal with a different part of the FAT32 filesystem? Like one for files, folders, etc. And if so, which is which?

I've been stuck on this for a while, so any help is greatly appreciated. Thank you very much. :)
