20 | .SH DESCRIPTION | |
21 | .I Ac | |
22 | produces a printout giving | |
23 | connect time | |
24 | for each user who has logged in | |
25 | during the life of the current | |
26 | .I wtmp | |
27 | file. | |
28 | A total is also produced. | |
29 | .B \-w | |
30 | is used to specify an alternate | |
31 | .IR wtmp "" | |
32 | file. | |
33 | .B \-p | |
34 | prints individual totals; without this option, | |
35 | only totals are printed. | |
36 | .B \-d | |
37 | causes a printout for each midnight to midnight | |
38 | period. | |
39 | Any | |
40 | .I people | |
41 | will limit the | |
42 | printout to only the specified login names. | |
43 | If no | |
44 | .IR wtmp "" | |
45 | file is given, | |
46 | .I /usr/adm/wtmp | |
47 | is used. | |
48 | .PP | |
49 | The accounting file | |
50 | .I /usr/adm/wtmp | |
51 | is maintained by | |
52 | .I init | |
53 | and | |
54 | .I login. | |
55 | Neither of these programs creates the file, | |
56 | so if it does not exist | |
57 | no connect-time accounting is done. | |
58 | To start accounting, it should be created with length 0. | |
59 | On the other hand if the file is left undisturbed it will | |
60 | grow without bound, so periodically any information | |
61 | desired should be collected and the file truncated. | |
