Compute using UNIX system

Create three new users. Document the commands you used to create the users.

Step 2

Create a new group named developers. Document the command you used to create the group.

Step 3

Add the three new users to the developers group, in a single command. Document the command you used to do this.

Step 4

Create a file named secretstuff.txt in the home directory of one of your new users. Set the permissions on this file so that only the user has read access to the file (group and world have no access whatsoever). Document your steps in completing this. Verify that the user can still read and write to this file, but others cannot access it.
