NAME¶

lastcomm - print out information about previously executed commands.

SYNOPSIS¶

lastcomm

[ command-name ... ]
[ user-name ... ]
[ terminal-name ... ]
[ --strict-match ]
[ -f filename | --file filename ]
[ --user name ] [ --command name ] [ --tty name ]
[ --debug ] [ -pid ] [ -V | --version ] [ -h | --help ]

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 a.out root 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

OPTIONS¶

--strict-match

Print only entries that match *all* of the arguments on the command line.

--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.

-f filename, --file filename

Read from the file filename instead of acct

--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.
