The Role of the 'chmod' Command in Linux

The 'chmod' command in Linux is used to change the permissions of files and directories. It allows system administrators to control who can read, write, or execute a file or directory. This command is essential for maintaining security and access control on a Linux system.

By using 'chmod', system administrators can specify permissions for the owner of the file, the group that the file belongs to, and other users. The permissions can be set to allow or restrict various actions such as reading, writing, and executing files.

Overall, the 'chmod' command plays a crucial role in managing the security and access permissions of files and directories in a Linux system, ensuring that sensitive data is protected and only authorized users can perform specific actions.
