36 .Nd show last commands executed
47 utility gives information on previously executed commands.
50 prints information about all the commands recorded
51 during the current accounting file's lifetime.
53 The following options are available:
54 .Bl -tag -width indent
56 Print the time the process exited.
58 Print the time the process started.
60 Print the amount of cpu time used by the process.
62 Print the amount of elapsed time used by the process.
64 Print the amount of system time used by the process.
66 Print the amount of user time used by the process.
70 rather than the default

107 For each process entry, the following are printed.
109 .Bl -bullet -offset indent -compact
111 The name of the user who ran the process.
113 Flags, as accumulated by the accounting facilities in the system.
115 The command name under which the process was called.
126 time used by the process (in seconds).
128 The time the process started
134 The flags are encoded as follows: ``S'' indicates the command was
135 executed by the super-user, ``F'' indicates the command ran after
136 a fork, but without a following
138 .\" ``C'' indicates the command was run in PDP-11 compatibility mode
140 ``D'' indicates the command terminated with the generation of a
142 file, and ``X'' indicates the command was terminated with a signal.
144 By default, accounting entries are printed going backwards in time,
145 starting from the time
150 reads entries from its standard input, then entries are printed in
151 the order they are read.
153 .Bl -tag -width /var/account/acct -compact

160 will print the exit time and elapsed time of each command logged in
161 .Pa /var/account/acct ,
163 .Dl tail -f -c 0 /var/account/acct | lastcomm -f -
164 will print details of each terminating command.
