.th WTMP V 9/10/73 .sh NAME wtmp \*- user login history .sh DESCRIPTION This file records all logins and logouts. Its format is exactly like utmp(V) except that a null user name indicates a logout on the associated typewriter, and the typewriter name `x' indicates that UNIX was rebooted at that point. .s3 Wtmp is maintained by login(I) and init(VII). Neither of these programs creates the file, so if it is removed record-keeping is turned off. .s3 This file resides in directory /tmp. .sh "SEE ALSO" init(VII), login(I)
