Who Can Change File’s Permissions?
(First of all the root User is the Default one in Kali, so this instruction is intended for a Normal User)
So to Check What User you are on:
- You Can Freely Change Permissions over Files/Directories Your User’s Hold.
- But you need Admin Super User Powers to Change Permissions on Entities he Do Not Hold!
Setting Up Permissions on Files and Directories
- 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)
- Use ‘x‘ to Setup Execution Permission
- Use ‘w‘ to Setup Write/Delete Permission
- Use ‘r‘ to Setup Read Permission
- Use ‘+‘ to Give Permission
- Use ‘–‘ to Remove Permission
Basic Building Blocks for the Permission Command
Generic Permission Command Form:
chmod ownershipSubject[+/-]r/w/x [myEntity]
For Instance :
To Give ‘All’ (read,write/delete,execute) Permissions on the ‘world’ Directory to ‘Everybody’:
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:
ls -l $HOME
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:
chmod g+x $HOME/world
(After Only You and Your Group will be Able to Access the ‘world’ Directory Directory on Shell!)
