4. rm - Remove: This command is used to delete files or directories. For example, rm file.txt will delete the file named "file.txt".

5. cp - Copy: This command copies files or directories. For example, cp file.txt ~/Documents will copy the file "file.txt" to the Documents directory.

6. mv - Move: This command moves files or directories. For example, mv file.txt ~/Documents will move the file "file.txt" to the Documents directory.
