LASTCOMM(1) NetBSD General Commands Manual LASTCOMM(1)
Powered by man-cgi (2021-06-01).

lastcomm -- show last commands executed in reverse order
lastcomm [-w] [-f file] [command ...] [user ...] [terminal ...]
lastcomm gives information on previously executed commands. With no
arguments, lastcomm prints information about all the commands recorded
during the current accounting file's lifetime.
-f file Read from file rather than the default accounting file.
-w Use as many columns as needed to print the output instead of
limiting it to 80.
If called with arguments, only accounting entries with a matching command
name, user name, or terminal name are printed. So, for example:
lastcomm a.out root ttyd0
would produce a listing of all the executions of commands named a.out by
user root on the terminal ttyd0.
For each process entry, the following are printed.
· The name of the user who ran the process.
· Flags, as accumulated by the accounting facilities in the sys-
· The command name under which the process was called.
· The amount of cpu time used by the process (in seconds).
· The time the process started.
· The elapsed time of the process.
The flags are encoded as follows: ``S'' indicates the command was exe-
cuted by the super-user, ``F'' indicates the command ran after a fork,
but without a following exec(3), ``C'' indicates the command was run in
PDP-11 compatibility mode (VAX only), ``D'' indicates the command termi-
nated with the generation of a core file, and ``X'' indicates the command
was terminated with a signal.
The ``S'' and ``C'' flags are no longer recorded by the system, but will
be reported by lastcomm when reading from an accounting file generated by
an older version of the system.
/var/account/acct Default accounting file.
last(1), sigaction(2), acct(5), core(5)
The lastcomm command appeared in 3.0BSD.
