====== Setting Automatic Group Permissions in a Directory ======

This page is to help someone who has a group who can edit certain files on a Linux machine, but you don't want to have to run chmod every time, you can set what they call the //set bit// for the group. To do this I will have to show you a command and explain what each part does. Each part that is Bold is something that you would need to change for your needs.  Please read the whole article before trying this!!!

The command is: 

<code>find your_directory_name_here -type d -exec chmod g+s '{}' ';'</code>

  * The ''find'' portion is the criteria to look within the specified directory.
  * ''your_directory_name_here'' is the directory that you will be looking in.

  * ''-type d'' says that you you will be looking for all directories in the folder specified before. 
  * ''-type f'' to find all of the files in the specified directory instead of ''-type d'' which is all of the directories 
  * ''-exec'' is needed to run a command in a command…don't worry about the details
  * ''chmod g+s'' - chmod is to change permissions on the folder that was specified before and the ''g+s'' says to set the //set bit// for the group. This just means when a file is created then the group who owns the file won't change. 

You can change this to any command that you want. If you want to change all of the files permissions then you would just type “chmod 775” rather than “chmod g+s” 
This is the same for setting the group. You would type ''chgrp group_name'' and they would be the group owners of the file. 
'''{}' ';''' these are the commands that have to end the command ''-exec''.

I have a suggestion before you just start running these commands. You may want to know that you have done this right and the best way is to run the ''echo'' command to see that you have selected the correct files. An example of this would be:

<code>find your_directory_name_here -type d -exec echo chmod g+s '{}' ';'</code>

Once you know that this is what you want, you will most likely have to use ''sudo'' to be able to change these files permissions. This is done by just replacing ''ech'' with ''sudo''. This is an example:

First:

<code>find your_directory_name_here -type d -exec echo chmod g+s '{}' ';'</code>

Second, after verifying this works:

<code>find your_directory_name_here -type d -exec sudo chmod g+s '{}' ';'</code>
