utmp
UTMP(5) BSD File Formats Manual UTMP(5)NAME
utmp, wtmp, lastlog -- login records (DEPRECATED)
SYNOPSIS
#include <utmp.h>
DESCRIPTION
The interfaces in file <utmp.h> are all DEPRECATED and are only provided for compatibility with previous releases of Mac OS X. See
pututxline(3) and utmpx(5) for the supported interfaces.
<utmp.h> declares the structures used to record information about current users in the file utmp, logins and logouts in the file wtmp, and
last logins in the file lastlog. The time stamps of date changes, shutdowns and reboots are also logged in the wtmp file.
These files can grow rapidly on busy systems, daily or weekly rotation is recommended. If any of these files do not exist, it is not cre-
ated. These files must be created manually and are normally maintained in either the script /etc/daily or the script /etc/weekly. (See
cron(8).)
#define _PATH_UTMP "/var/run/utmp"
#define _PATH_WTMP "/var/log/wtmp"
#define _PATH_LASTLOG "/var/log/lastlog"
#define UT_NAMESIZE 8
#define UT_LINESIZE 8
#define UT_HOSTSIZE 16
struct lastlog {
time_t ll_time;
char ll_line[UT_LINESIZE];
char ll_host[UT_HOSTSIZE];
};
struct utmp {
char ut_line[UT_LINESIZE];
char ut_name[UT_NAMESIZE];
char ut_host[UT_HOSTSIZE];
time_t ut_time;
};
Each time a user logs in, the login program looks up the user's UID in the file lastlog. If it is found, the timestamp of the last time the
user logged in, the terminal line and the hostname are written to the standard output. (Providing the login is not quiet, see login(1).) The
login program then records the new login time in the file lastlog.
After the new lastlog record is written , the file utmp is opened and the utmp record for the user inserted. This record remains there until
the user logs out at which time it is deleted. The utmp file is used by the programs rwho(1), users(1), w(1), and who(1).
Next, the login program opens the file wtmp, and appends the user's utmp record. The same utmp record, with an updated time stamp is later
appended to the file when the user logs out. (See launchd(8).) The wtmp file is used by the programs last(1) and ac(8).
In the event of a date change, a shutdown or reboot, the following items are logged in the wtmp file.
reboot
shutdown A system reboot or shutdown has been initiated. The character '~' is placed in the field ut_line, and reboot or shutdown in the
field ut_name. (See shutdown(8) and reboot(8).)
date The system time has been manually or automatically updated. (See date(1).) The command name date is recorded in the field
ut_name. In the field ut_line, the character '|' indicates the time prior to the change, and the character '{' indicates the new
time.
FILES
(These files no longer exist in 10.5 or later.)
/var/run/utmp The utmp file.
/var/log/wtmp The wtmp file.
/var/log/lastlog The lastlog file.
SEE ALSO last(1), login(1), who(1), ac(8), launchd(8)HISTORY
A utmp and wtmp file format appeared in Version 6 AT&T UNIX. The lastlog file format appeared in 3.0BSD.
