| 7 | SYNOPSIS login\b\b\b\b\b_____ [ username [ password ] ] | |
| 8 | .sp | |

| 10 | DESCRIPTION The login\b\b\b\b\b_____ command | |
| 11 | is used when a user initially | |
| 12 | signs onto UNIX, or it may be used at any time to change | |
| 13 | from one user to another. | |
| 14 | The latter case is the one summarized above and | |
| 15 | described here. | |
| 16 | See login\b\b\b\b\b_____ (VII) for how to dial up initially. | |
| 17 | ||
| 18 | If login\b\b\b\b\b_____ is invoked without an argument, | |
| 19 | it will ask for a user name, and, if | |
| 20 | appropriate, a password. | |
| 21 | Echoing is turned off (if possible) during the typing of the password, | |
| 22 | so it will not appear on the written record of the | |
| 23 | session. | |
| 24 | .sp | |
| 25 | After a successful login, | |
| 26 | accounting files are updated and | |
| 27 | the user is informed of the | |
| 28 | existence of mailbox | |
| 29 | and message-of-the-day files. | |
| 30 | ||
| 31 | Login is recognized by the Shell | |
| 32 | and executed directly (without forking). | |
