LASTCOMM(1)	    UNIX Programmer's Manual	      LASTCOMM(1)



NAME
     lastcomm - show last commands executed in reverse order

SYNOPSIS
     lastcomm [ -f file ] [ command name ] ... [user name] ...
     [terminal name] ...

DESCRIPTION
     _L_a_s_t_c_o_m_m gives information on previously executed commands.

     Option:


     -f _f_i_l_e   Read from _f_i_l_e rather than the default accounting
	       file.

     With no arguments, _l_a_s_t_c_o_m_m prints information about all the
     commands recorded during the current accounting file's life-
     time.  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._o_u_t by user _r_o_o_t on the terminal _t_t_y_d_0.

     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 system.
	  The command name under which the process was called.
	  The amount of cpu time used by the process (in
	  seconds).
	  The time the process exited.

     The flags are encoded as follows: ``S'' indicates the com-
     mand was executed by the super-user, ``F'' indicates the
     command ran after a fork, but without a following _e_x_e_c,
     ``C'' indicates the command was run in PDP-11 compatibility
     mode (VAX only), ``D'' indicates the command terminated with
     the generation of a _c_o_r_e file, and ``X'' indicates the com-
     mand was terminated with a signal.

FILES
     /usr/adm/acct	 Default accounting file.
