lastcomm - show last commands executed in reverse order
lastcomm [-f file] [command ...] [user ...] [terminal ...]
lastcomm gives information on previously executed commands.
With no arguments,
lastcomm prints information about all the commands
the current accounting file's lifetime.
The options are as follows:
Read from file rather than the default accounting
If called with arguments, only accounting entries with a
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 Name of the user who ran the process.
+o Flags, as accumulated by the system's accounting
+o Command name under which the process was called.
+o Amount of CPU time used by the process (in seconds).
+o Time the process started.
+o Elapsed time of the process.
The flags are encoded as follows: `S' indicates the command
by the superuser, `F' indicates the command ran after a
fork, but without
a following exec(3), `C' indicates the command was run in
mode (VAX only), `D' indicates the command terminated
generation of a core file, and `X' indicates the command was
with a signal.
/var/account/acct default accounting file
last(1), sigvec(3), acct(5), core(5), accton(8)
The lastcomm command appeared in 3.0BSD.
