LASTCOMM(1) BSD Reference Manual LASTCOMM(1)
lastcomm - show last commands executed in reverse order
lastcomm [-f file] [command ...] [user ...] [terminal ...]
Lastcomm gives information on previously executed commands. With no ar-
guments, lastcomm prints information about all the commands recorded dur-
ing the current accounting file's lifetime.
-f file Read from file rather than the default accounting file.
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.
o The name of the user who ran the process.
o Flags, as accumulated by the accounting facilities in the sys-
o The command name under which the process was called.
o The amount of cpu time used by the process (in seconds).
o The time the process exited.
The flags are encoded as follows: ``S'' indicates the command was execut-
ed by the super-user, ``F'' indicates the command ran after a fork, but
without a following exec, ``C'' indicates the command was run in PDP-11
compatibility mode (VAX only), ``D'' indicates the command terminated
with the generation of a core file, and ``X'' indicates the command was
terminated with a signal.
/var/account/acct Default accounting file.
last(1), sigvec(2), acct(5), core(5)
The lastcomm command appeared in 3.0BSD.
