40 .Nd show last commands executed
51 utility gives information on previously executed commands.
54 prints information about all the commands recorded

57 The following options are available:
58 .Bl -tag -width indent
60 Print the time the process exited.
62 Print the time the process started.
64 Print the amount of cpu time used by the process.
66 Print the amount of elapsed time used by the process.

119 The command name under which the process was called.
130 time used by the process (in seconds).
132 The time the process started

139 executed by the super-user, ``F'' indicates the command ran after
140 a fork, but without a following
142 .\" ``C'' indicates the command was run in PDP-11 compatibility mode
144 ``D'' indicates the command terminated with the generation of a
146 file, and ``X'' indicates the command was terminated with a signal.
148 By default, accounting entries are printed going backwards in time,
149 starting from the time
