Changing AFS permissions for SUBDIRECTORIES of a DIRECTORY
Setting AFS permissions in a directory using "fs sa" will not
automatically change the permissions in the subdirectories that
already exist in that directory. If you want to change the
permissions in all of the subdirectories as well, you have two options:
1) The easiest method is to use the "fsr" command in the consult
locker. This command is a wrapper around the "fs" command and takes
the same arguments, but will change permissions in a given directory
and all its subdirectories.
For example:
To give a user permissions on one directory (but not its
subdirectories) you would do:
athena% fs sa directoryname username permissions
like so:
athena% fs sa ~/www joeuser write
To set the permissions recursively, you'd simply replace "fs" with
"fsr". You will need to have the consult locker "added" already:
athena% add consult
athena fsr sa ~/www joeuser write
As is the case any time you change AFS permissions, you should inspect
the end result with "fs la" to ensure that the permissions are set as
you intended.
2) The other option is to use the the "find" command, which traverses
a directory structure and finds all the things that match.
If you wanted to give the user permissions in a directory and all its
subdirectories, you would do:
athena% find dirname -type d -exec fs sa {} username permission \;
like so:
athena% find ~/www -type d -exec fs sa {} joeuser write \;
(In English, that would be "Find everything in the www directory that
is of type "d", that is, also a directory, and then execute the
following "fs sa" command on it, filling in the directories you've
found in place of the {}s")
Similarly, if you wanted to give permissions to a group instead, you
would do something like
athena% find ~/MySecretFiles -type d -exec fs sa {} system:myfriends read \;
