What is Permission?
When you use a system, whether it is Linux or any other, many important files are kept inside folders. But only saving a file in a folder does not make it safe.
In Linux, you must set permissions like read, write, and execute. If permissions are set, your file cannot be changed or misused by others.
Types of Permissions:
- Read (r)
- Write (w)
- Execute (x)
Permission Levels:
In Linux, permission levels define different types of users and decide what permissions each user can get. According to the requirement, permissions are assigned to different users, such as read, write, or execute. In this way, permission levels control which user can access a file or directory and what actions they can perform on it.
List of Permission Levels:
- User (u)
- Group (g)
- Others (o)
