Имя (Name)

lastcomm - print out information about previously executed commands.

---

Синопсис (Synopsis)

lastcomm [ command-name ... ] [ 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.
