Can nay one tell me what is sudo command? What are syntax to use sudo command. When sudo command executed user login required with superuser or another user?

[Calvin K]

Macintosh computers do not use sudo as Mac uses the UNIX system.sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file. The su (short for substitute user) command makes it possible to change a login session's owner.

[Lillebror]

The sudo command is a program for some Unix and Unix-like computer operating systems that allows users to run programs with the security privileges of another user.sudo can log both successful and unsuccessful attempts (as well as errors) to syslog(3), a log file, or both.

[Wynn]

Many other Unixes, and Linux, use "sudo".The configuration of sudo is by the /etc/sudoers file. Sudo allows a user with proper permissions to execute a command as the superuser or other user. The advantage of using su is that a record is kept of its usage in system logs, whereas no such record is kept if one logs in directly as root. It prompts you for your personal password and confirms your request to execute a command by checking a file, called sudoers.
