11 [ user-name ... ]
12 [ terminal-name ... ]
13 [ OPTION ... ]

16 lastcomm prints out information about previously executed commands. If
17 no arguments are specified, lastcomm will print info about all of the
18 commands in acct (the record file). If called with one or more of com‐
19 mand-name, user-name, or terminal-name, only records containing those
20 items will be displayed. For example, to find out which users used
21 command `a.out' and which users were logged into `tty0', type:
22 lastcomm a.out tty0
23 This will print any entry for which `a.out' or `tty0' matches in any of
25 the record's fields (command, name, or terminal). If you want to find
26 only items that match *all* of the arguments on the command line, you
27 must use the '-strict-match' option. For example, to list all of the
28 executions of command a.out by user root on terminal tty0, type:
29 lastcomm --strict-match --command a.out --user root --tty tty0
30 The order of the arguments is not important.
32 For each entry the following information is printed:
34 + command name of the process
35 + flags, as recorded by the system accounting routines:
36 S -- command executed by super-user
37 F -- command executed after a fork but without a following exec
38 C -- command run in PDP-11 compatibility mode (VAX only)
39 D -- command terminated with the generation of a core file
40 X -- command was terminated with the signal SIGTERM
41 + the name of the user who ran the process
42 + time the process started
43
45 --strict-match
46 Print only entries that match *all* of the arguments on the com‐
47 mand line.
48 --print-controls
49 Print control characters.
50 --user name
51 List records for user with name. This is useful if you're try‐
52 ing to match a username that happens to be the same as a command
53 (e.g., ed ).
54 --command name
55 List records for command name.
56 --tty name
57 List records for tty name.
58 --forwards
59 Read file forwards instead of backwards. This avoids trying to
60 seek on the file and can be used to read from a pipe. This must
61 be specified prior to any -f arguments.
62 -f filename, --file filename
63 Read from the file filename instead of acct. A filename of "-"
64 will result in reading from stdin. This must either be the first
65 -f option, or --forwards must precede all -f options.
66 --ahz hz
67 Use this flag to tell the program what AHZ should be (in hertz).
68 This option is useful if you are trying to view an acct file
69 created on another machine which has the same byte order and
70 file format as your current machine, but has a different value
71 for AHZ.
72 -p, --show-paging
73 Print paging statistics.
74 --pid Show PID and PPID of the process if acct version 3 format is
75 supported by kernel.
76 --debug
77 Print verbose internal information.
78 -V, --version
79 Print the version number of lastcomm.
80 -h, --help
81 Prints the usage string and default locations of system files to
82 standard output and exits.
83
85 acct
86 The system wide process accounting file. See acct(5) (or pac‐
87 ct(5)) for further details. /var/log/account
88 This directory contains pacct files which contain the bi‐
89 nary process accounting data as written by the kernel.
91 The GNU accounting utilities were written by Noel Cragg
92 <noel@gnu.ai.mit.edu>. The man page was adapted from the accounting
93 texinfo page by Susan Kleinmann <sgk@sgk.tiac.net>.
