1. What are special permissions in RHEL?
Ans. Special permissions in RHEL (Red Hat Enterprise Linux) refer to the additional permission settings that can be applied to files and directories. These permissions include the setuid, setgid, and sticky bit.
2. How does the setuid permission work in RHEL?
Ans. The setuid permission in RHEL allows a user to execute a program with the permissions of the owner of that program. When a program with the setuid permission is executed, it runs with the privileges of the owner, rather than the privileges of the user who executed it.
3. What is the purpose of the setgid permission in RHEL?
Ans. The setgid permission in RHEL allows files and directories to inherit the group ownership of the parent directory. When a new file or directory is created within a directory with the setgid permission, it automatically inherits the group ownership of the parent directory.
4. How does the sticky bit permission work in RHEL?
Ans. The sticky bit permission in RHEL is primarily used for directory permissions. When the sticky bit is set on a directory, only the owner of a file within that directory can delete or rename the file. This is commonly used for shared directories to prevent users from accidentally deleting or modifying others' files.
5. How can special permissions be set in RHEL?
Ans. Special permissions can be set in RHEL using the chmod command. For example, to set the setuid permission, you can use "chmod u+s filename" and for setgid permission, you can use "chmod g+s filename". To set the sticky bit permission, you can use "chmod +t directoryname".
