Linux permissions

[LooseCaboose]

Read only for who? Normal users should only have read/write access in their /home directory, /tmp and possibly something like /local. If you need to write files elsewhere it should be done as root.

If you really need to change permissions for a directory (and make sure you really want to since Unix file permissions are that way for a reason) you can do this:

Code:

chmod a+wrX -R some_directory

Which will recursively apply read/write permissions (with execute for all things which already have it) to the given directory. It is fairly rare that you would want to do this though.
