19 lastcomm prints out information about previously executed commands. If
20 no arguments are specified, lastcomm will print info about all of the
21 commands in acct (the record file). If called with one or more of com‐
22 mand-name, user-name, or terminal-name, only records containing those
23 items will be displayed. For example, to find out which users used
24 command `a.out' and which users were logged into `tty0', type:
25 lastcomm a.out tty0
26 This will print any entry for which `a.out' or `tty0' matches in any of
28 the record's fields (command, name, or terminal). If you want to find
29 only items that match *all* of the arguments on the command line, you
30 must use the '-strict-match' option. For example, to list all of the
31 executions of command a.out by user root on terminal tty0, type:
32 lastcomm --strict-match a.out root tty0
33 The order of the arguments is not important.
35 For each entry the following information is printed:
37 + command name of the process
38 + flags, as recorded by the system accounting routines:
39 S -- command executed by super-user
40 F -- command executed after a fork but without a following exec
41 C -- command run in PDP-11 compatibility mode (VAX only)
42 D -- command terminated with the generation of a core file
43 X -- command was terminated with the signal SIGTERM
44 + the name of the user who ran the process
45 + time the process started
46
48 --strict-match
49 Print only entries that match *all* of the arguments on the com‐
50 mand line.
51 --user name
53 List records for user with name. This is useful if you're try‐
54 ing to match a username that happens to be the same as a command
55 (e.g., ed ).
56 --command name
58 List records for command name.
59 --tty name
61 List records for tty name.
62 -f filename, --file filename
64 Read from the file filename instead of acct
65 --pid add pid of the process and pid of the process parent to the out‐
67 put (pid is the last but one and parent pid the last column).
68 These values are shown only when they are generated by acct
69 function (depends on the version of kernel)
70 --debug
72 Print verbose internal information.
73 -V, --version
75 Print the version number of lastcomm.
76 -h, --help
78 Prints the usage string and default locations of system files to
79 standard output and exits.
80
83 acct
84 The system wide process accounting file. See acct(5) (or pac‐
85 ct(5)) for further details.
