For Instance :

To Remove the ‘Write/Delete’ Permission to the ‘World’:
chmod a-w $HOME/world
To Give the ‘Write/Delete’ Permission the ‘world’ Only to the Owner:
chmod u+w $HOME/world
To Give the ‘Write/Delete’ Permission the ‘world’ Also to the Owner’s Group:
chmod g+w $HOME/world
To Remove the ‘Execution’ Permission to the ‘World’:
chmod a-x $HOME/world
To Give the ‘Execution’ Permission to the ‘world’ to the Owner:
chmod u+x $HOME/world
To Give the ‘Execution’ Permission to the ‘world’ Also to the Owner’s Group:
