Синопсис (Synopsis)

[ user-name ... ]
[ terminal-name ... ]
[ OPTION ... ]
Описание (Description)
lastcomm
prints out information about previously executed
commands. If no arguments are specified, lastcomm
will print
info about all of the commands in acct (the record file). If
called with one or more of command-name, user-name, or terminal-
name, only records containing those items will be displayed. For
example, to find out which users used command `a.out' and which
users were logged into `tty0', type:
lastcomm a.out tty0
This will print any entry for which `a.out' or `tty0' matches in
any of the record's fields (command, name, or terminal). If you
want to find only items that match *all* of the arguments on the
command line, you must use the '-strict-match' option. For
example, to list all of the executions of command a.out by user
root on terminal tty0, type:
lastcomm --strict-match --command a.out --user root --tty tty0
The order of the arguments is not important.
For each entry the following information is printed:
+ command name of the process
+ flags, as recorded by the system accounting routines:
S -- command executed by super-user
F -- command executed after a fork but without a
following exec
C -- command run in PDP-11 compatibility mode (VAX only)
D -- command terminated with the generation of a core
file
X -- command was terminated with the signal SIGTERM
+ the name of the user who ran the process
+ time the process started
Параметры (Options)
--strict-match
Print only entries that match *all* of the arguments on
the command line.
--print-controls
Print control characters.
--user
name
List records for user with name. This is useful if you're
trying to match a username that happens to be the same as
a command (e.g., ed ).
--command
name
List records for command name.
--tty
name
List records for tty name.
--forwards
Read file forwards instead of backwards. This avoids
trying to seek on the file and can be used to read from a
pipe. This must be specified prior to any -f
arguments.
-f
filename, --file
filename
Read from the file filename instead of acct. A filename
of "-" will result in reading from stdin. This must either
be the first -f
option, or --forwards
must precede all -f
options.
--ahz
hz
Use this flag to tell the program what AHZ
should be (in
hertz). This option is useful if you are trying to view
an acct file created on another machine which has the same
byte order and file format as your current machine, but
has a different value for AHZ.
-p, --show-paging
Print paging statistics.
--pid
Show PID and PPID of the process if acct version 3 format
is supported by kernel.
--pid
Add pid of the process and pid of the process parent to
the output (pid is the last but one and parent pid the
last column). These values are shown only when they are
generated by acct function (depends on the version of
kernel)
--debug
Print verbose internal information.
-V, --version
Print the version number of lastcomm.
-h, --help
Prints the usage string and default locations of system
files to standard output and exits.
Файлы (Files)
acct
The system wide process accounting file. See acct(5) (or
pacct
(5)) for further details. /var/log/account
This directory contains pacct files which contain
the binary process accounting data as written by
the kernel.
