umask settings for airborne group on citation2

umask sets the default file permissions. It is usually set at 0022, but we want 0002. This gives 'airborne' group write access to all files and folders. For security reasons, we don't want to have group write access on just any computer, so follow the instructions just for citation2. We should be doing processing of full aircraft flights and reprocessing of field projects only on Aircraft. Small-scale changes and algorithm/processing code development can still be run on data through your local computer, but double-check that permissions are consistent with other files when you are done.

1. Login to the username@aircraft.atmos.und.edu
2. Open .profile (in your home directory) with vi .profile
3. Add umask 0002 to the file and save it
4. Logout
5. When you log back on, you will then have group write access
6. Check to see that it has worked by typing umask in the terminal window

Now,

1. Open .bashrc (in your home directory) with vi .bashrc
2. Add umask 0002 to the file and save it
3. Close the terminal and open a new one
4. ssh into another computer on the network (i.e. username@nuclei.atmos.und.edu)
5. Check to see that it has worked by typing umask in the terminal window
