    User Commands

    adduser

    sudo adduser the-name-of-user-you-want
    

    password is optional

    the new user will be in the home directory

    chmod

    this command changes the permissions of types of users with regards to access to files and folders

    For the use of this command, three things need to be set, who you are setting the permission for, how you are setting it and to what are you setting it

    Who we are setting permissions to:

    u : owner of the file
    g : the file group
    o : everyone who is not an owner
    a : everyone

    How we are setting the permissions:

    + : turns on a permission
    - : turns off a permission
    = : ignores current permissions and sets  new on

    What we are setting them to:

    r : read
    w : write
    x : execute
    X : special execute for folders

     

    Now let's grant execute permissions to the user of a fictitious file.

    note, you may need to use sudo (if you are not the owner of the file)

    chmod u+x some_file.txt

    passwd

    allows you to change your password

    a user with sudo permission can change a different user's password
