lastcomm - show last commands executed in reverse order
lastcomm [ -f file ] [ command name ] ... [user name] ... [terminal name] ...
Lastcomm gives information on previously executed commands.
-f file Read from file rather than the default accounting file.
With no arguments, lastcomm prints information about all the commands recorded during the
current accounting file's lifetime. If called with arguments, only accounting entries
with a matching command name, user name, or terminal name are printed. So, for example,

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 command was executed 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.
/usr/adm/acct Default accounting file.
