3. Setting Up Permissions on Files and Directories.

   Basic Building Blocks for the Permission Command.

   Ownership Types:

   • Use ‘u‘ to Setup Permissions for the User Owner
   • Use ‘g‘ to Setup Permissions for the Group Owner
   • Use ‘u+g‘ to Setup Permissions for the User and Group Owner
   • Use ‘a‘ to Setup Permissions for All (World)
   • Use ‘o‘ for Revoking Actual Permissions and Giving Permissions to the Others (the Before Disabled ones)

   Permission Types:

   • Use ‘x‘ to Setup Execution Permission
   • Use ‘w‘ to Setup Write/Delete Permission
   • Use ‘r‘ to Setup Read Permission

   Giving/Removing Permissions:

   • Use ‘+‘ to Give Permission
   • Use ‘–‘ to Remove Permission

   Generic Permission Command Form:

   Copy

   chmod ownershipSubject[+/-]r/w/x [myEntity]

   For Instance :

   Copy

   mkdir $HOME/world

   To Give ‘All’ (read,write/delete,execute) Permissions on the ‘world’ Directory to ‘Everybody’:

   Copy

   chmod a+rwx $HOME/world

   (Normally Take Care Before to Open a Directory to the World Because this Can Compromise your System Security!)
   Now to Check Permissions Setup:

   Copy

   ls -l $HOME

   To Remove the ‘Write/Delete’ Permission to the ‘World’:

   Copy

   chmod a-w $HOME/world

   To Give the ‘Write/Delete’ Permission the ‘world’ Only to the Owner:

   Copy

   chmod u+w $HOME/world

   To Give the ‘Write/Delete’ Permission the ‘world’ Also to the Owner’s Group:

   Copy

   chmod g+w $HOME/world

   To Remove the ‘Execution’ Permission to the ‘World’:

   Copy

   chmod a-x $HOME/world

   To Give the ‘Execution’ Permission to the ‘world’ to the Owner:

   Copy

   chmod u+x $HOME/world

   To Give the ‘Execution’ Permission to the ‘world’ Also to the Owner’s Group:

   Copy

   chmod g+x $HOME/world

   (After Only you and your Group will be able to Access the ‘world’ Directory Directory on Shell!)
