LASTCOMM(1) General Commands Manual LASTCOMM(1) NAME lastcomm -- show last commands executed in reverse order SYNOPSIS lastcomm [-w] [-f file] [command ...] [user ...] [terminal ...] DESCRIPTION lastcomm gives information on previously executed commands. With no arguments, lastcomm prints information about all the commands recorded during the current accounting file's lifetime. Option: -f file Read from file rather than the default accounting file. -w Use as many columns as needed to print the output instead of limiting it to 80. 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.out by user root on the terminal ttyd0. For each process entry, the following are printed. o The name of the user who ran the process. o Flags, as accumulated by the accounting facilities in the system. o The command name under which the process was called. o The amount of cpu time used by the process (in seconds). o The time the process started. o The elapsed time of the process. 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(3), ``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. The ``S'' and ``C'' flags are no longer recorded by the system, but will be reported by lastcomm when reading from an accounting file generated by an older version of the system. FILES /var/account/acct Default accounting file. SEE ALSO last(1), sigaction(2), acct(5), core(5) HISTORY The lastcomm command appeared in 3.0BSD. NetBSD 7.1.2 January 31, 2012 NetBSD 7.1.2
