लाइनक्स में लॉग-इन और लॉग-आउट करने की विधियाँ लिखिए। या लॉग-इन प्रक्रिया क्या है?

Answer 1

• login is a UNIX command for logging into a UNIX system.
• login is a builtin command in csh. There is also an external utility with the same name and functionality.
• In many modern systems, the functionality of login is hidden from the user. The login command runs automatically upon connection. In some old computers you may need to type a special character or even type login to bring up the login program.
• If you login remotely to a server you will be prompted for your user/account name and password. If you start up a terminal emulator and shell from a graphic user interface you will probably already be authenticated and immediately go to the shell (although some of the startup activity of login will still be done for you).
• When you finish using the shell, type the exit or logout command. This will either display a new login prompt or close the terminal emulator window. if you are logged in remotely to a server, this will break your connection. If you are logged in physically on a large UNIX system, this will prevent someone else from abusing your account.
• When you finish using the shell, type the exit or logout command. This will either display a new login prompt or close the terminal emulator window.
• Some of the possible variations of this command include: bye, exit, lo, logout, and quit.
