What is the usage of the sudo command in Linux?

In the Linux system, the sudo command allows regular users to execute specific commands with superuser privileges. This allows users to temporarily gain root access without switching users in order to perform tasks that require privileged permissions.

The usage of sudo is:

sudo [option] command

Option refers to some choices, while command is the action to be executed. For example, to view the content of a specific directory with root privileges, you can use the following command:

sudo ls /path/to/directory

When executing the sudo command, the system will prompt for the current user’s password to confirm their identity. Only when the correct password is entered, can the corresponding command be executed with superuser privileges.
