group permissions

[mviverette]

how can i create user groups that have permissions to read only a specific directory in the web folder on my rh7.3 box.

for example. lets say i have folders and usernames as follows:
-[directory] - [users able to access directory]
-/www/html - users root, matt, jack
-/www/html/thisdirectory - users john, doe
-/www/html/thisdirectory/thisdirectory - users pocahontas
-/www/html/thisotherdir - users b1, b2

how can i do this from the command prompt.

also, will all of these people be able to ftp into their correct directory? remember, i want all of these people to have complete access but to their directory only... no other directories, with the exception of root, matt, and jack, which i want to have universal access to all directories all the way down the hierarchy.

thanks for any help you may provide!

You would probably want to use the chmod command. This can explain things a lot better than I could:
