Im on Fedora Core 2 and fairly new to the group functions in linux. Basically I need to create a main folder with many sub folders inside the main folder. I need to give full read,write access to one account on the main and sub folders. Then I need to give read,write access to different accounts for different sub folders. So how would I go about doing that? Each account needs to have their own sub folder but I also need one main account that has full read write access to the main and sub folders as well. Would I create one group and give full read,write access for that group for all folders and then give individual accounts full read.write access to their appropriate sub folders along with the main group permissions?

Are you saying that you wnat one user to have read/write permissions for the directory and all sub directories? Then have a read/wirte permissions for a single group for each sub-directory? Then have no access for world (everyone else)? If so you can do this.

chmod -R 770 <directory> This will give the user and group read/write access.
chown -R root <directory> This will set root as the owner for all sud-directories and file in the parent directory.

then cd into the directory. You will need to do this for each directory.
chown -R :<group name> <directotry> This will set the group to all sub-directories and and file.

If you want MS like permissions where multiable groups and users ave different permissions for the same directories check out this link.

I think it is the other way around. I need a group to have read write access to main folder and sub folders. Then for each sub folder I want to specify a single user account to have read/write access to that specific sub folder. Basically Im setting up a web server for a website. different people will be logging in to access their sub folders to edit their files, but I also need one main account that has read/write access to all folders.

Example:

folder a
subfolder b

account x
account y

subfolder b is located in folder a. account x should have full access to folder a and subfolder b. account y should only have full access to subfolder b.

I thought the solution would be account x is a group and account y is a single account. Is that a correct way of doing it?

K, now I understand.

chmod -R 770 foldera Give r/w to user and group
chown y:x subfolderb Give user y r/w and group x r/w

I would say that is the way to do it.
