LASTCOMM(1)             NetBSD General Commands Manual             LASTCOMM(1)


NAME
lastcomm -- show last commands executed in reverse order
SYNOPSIS
lastcomm [-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. 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. · The name of the user who ran the process. · Flags, as accumulated by the accounting facilities in the sys- tem. · The command name under which the process was called. · The amount of cpu time used by the process (in seconds). · The time the process started. · The elapsed time of the process. The flags are encoded as follows: ``S'' indicates the command was exe- cuted 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 termi- nated 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.
