What is the purpose of the Linux sudo command?

The sudo command is a crucial command in the Linux system, allowing regular users to execute specific commands or access certain files as the superuser (root). In particular, the sudo command can fulfill several functions:

1. Increasing permissions: Regular users can use the sudo command to elevate their privileges to superuser level when executing commands to perform operations that require root access.
2. Authorization management: System administrators can use the sudo command to determine which regular users can execute commands as root, thereby managing the permissions of users.
3. Security control: The sudo command can record every command executed by a user and write it to the system log, allowing for tracking of user actions and enhancing system security.

In general, the purpose of the sudo command is to grant specific tasks to regular users while ensuring system security, to avoid potential risks associated with direct use of superuser privileges.
