| 15 | _\bW_\bh_\bo, without any argument, reads the /etc/utmp file, and | |
| 16 | lists the login name, terminal name, and login time for each | |
| 17 | user currently logged into the system. If a single argument | |
| 18 | is given, _\bw_\bh_\bo uses that file instead of /etc/utmp. Typi- | |
| 19 | cally, that file will be /usr/adm/wtmp, which contains a | |
| 20 | record of all the logins, logouts, crashes, shutdowns and | |
| 21 | time changes since it was created. In either case, each | |
| 22 | login will be listed with the user name, the terminal name | |
| 23 | (with "/dev/" suppressed), login date and time, and, if | |
| 24 | applicable, the host logged in from. | |
| 25 | ||
| 26 | If /usr/adm/wtmp is being used as the file, the user name | |
| 27 | may be empty or one of the special characters '|', '}' and | |
| 28 | '~'. Logouts produce an output line without any user name. | |
| 29 | For more information on the special characters, see utmp(5). | |
| 30 | ||
| 31 | With two arguments, as in `who am I' (and also `who are | |
| 32 | you'), _\bw_\bh_\bo tells you who you are logged in as. | |
