!!DESCRIPTION |
|
|
26 |
|
|
|
27 |
|
|
|
28 |
__Last__ searches back through the file |
|
|
29 |
__/var/log/wtmp__ (or the file designated by the |
|
|
30 |
__-f__ flag) and displays a list of all users logged in |
|
|
31 |
(and out) since that file was created. Names of users and |
|
|
32 |
tty's can be given, in which case __last__ will show only |
|
|
33 |
those entries matching the arguments. Names of ttys can be |
|
|
34 |
abbreviated, thus __last 0__ is the same as __last |
|
|
35 |
tty0__. |
|
|
36 |
|
|
|
37 |
|
|
|
38 |
When __last__ catches a SIGINT signal |
|
|
39 |
(generated by the interrupt key, usually control-C) or a |
|
|
40 |
SIGQUIT signal (generated by the quit key, |
|
|
41 |
usually control-), __last__ will show how far it has |
|
|
42 |
searched through the file; in the case of the |
|
|
43 |
SIGINT signal __last__ will then |
|
|
44 |
terminate. |
|
|
45 |
|
|
|
46 |
|
|
|
47 |
The pseudo user __reboot__ logs in each time the system |
|
|
48 |
is rebooted. Thus __last reboot__ will show a log of all |
|
|
49 |
reboots since the log file was created. |
|
|
50 |
|
|
|
51 |
|
|
|
52 |
__Lastb__ is the same as __last__, except that by |
|
|
53 |
default it shows a log of the file __/var/log/btmp__, |
|
|
54 |
which contains all the bad login attempts. |

|
|

__-__''num'' |
|
|
59 |
|
|
|
60 |
|
|
|
61 |
This is a count telling __last__ how many lines to |
|
|
62 |
show. |
|
|
63 |
|
|
|
64 |
|
|
|
65 |
__-n__ ''num'' |
|
|
66 |
|
|
|
67 |
|
|
|
68 |
The same. |

|
|
|
71 |
__-R__ |
|
|
72 |
|
|
|
73 |
|
|
|
74 |
Suppresses the display of the hostname field. |
|
|
75 |
|
|
|
76 |
|
|
|
77 |
__-a__ |
|
|
78 |
|
|
|
79 |
|
|
|
80 |
Display the hostname in the last column. Useful in |
|
|
81 |
combination with the next flag. |
|
|
82 |
|
|
|
83 |
|
|
|
84 |
__-d__ |
|
|
85 |
|
|
|
86 |
|
|
|
87 |
For non-local logins, Linux stores not only the host name of |
|
|
88 |
the remote host but its IP number as well. This option |
|
|
89 |
translates the IP number back into a hostname. |
|
|
90 |
|
|
|
91 |
|
|
|
92 |
__-i__ |
|
|
93 |
|
|
|
94 |
|
|
|
95 |
This option is like __-d__ in that it displays the IP |
|
|
96 |
number of the remote host, but it displays the IP number in |
|
|
97 |
numbers-and-dots notation. |
|
|
98 |
|
|
|
99 |
|
|
|
100 |
__-o__ |
|
|
101 |
|
|
|
102 |
|
|
|
103 |
Read an old-type wtmp file (written by linux-libc5 |
|
|
104 |
applications). |
|
|
105 |
|
|
|
106 |
|
|
|
107 |
__-x__ |
|
|
108 |
|
|
|
109 |
|
|
|
110 |
Display the system shutdown entries and run level |
|
|
111 |
changes. |
|
|
112 |
!!NOTES |
|
|
113 |
|
|
|
114 |
|
|
|
115 |
The files ''wtmp'' and ''btmp'' might not be found. |
|
|
116 |
The system only logs information in these files if they are |
|
|
117 |
present. This is a local configuration issue. If you want |
|
|
118 |
the files to be used, they can be created with a simple |
|
|
119 |
touch(1) command (for example, ''touch |
|
|
120 |
/var/log/wtmp''). |
