LASTCOMM(1) BSD 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 gener- ated by an older version of the system. FILES

lastcomm(1) User Commands lastcomm(1) NAME
lastcomm - display the last commands executed, in reverse order SYNOPSIS
lastcomm [-f file] [-x] [command-name] ... [user-name] ... [terminal-name] ... DESCRIPTION
The lastcomm command gives information on previously executed commands. lastcomm with no arguments displays information about all the com- mands recorded during the current accounting file's lifetime. If called with arguments, lastcomm only displays accounting entries with a matching command-name, user-name, or terminal-name. If extended process accounting is active (see acctadm(1M)) and is recording the appro- priate data items, lastcomm attempts to take data from the current extended process accounting file. If standard process accounting is active, lastcomm takes data from the current standard accounting file (see acct(2)). If terminal-name is `- -', there was no controlling TTY for the process. The process was probably executed during boot time. If terminal- name is `??', the controlling TTY could not be decoded into a printable name. For each process entry, lastcomm displays the following items of information: o The command name under which the process was called. o One or more flags indicating special information about the process. The flags have the following meanings: F The process performed a fork but not an exec. S The process ran as a set-user-id program. o The name of the user who ran the process. o The terminal which the user was logged in on at the time (if applicable). o The amount of CPU time used by the process (in seconds). o The date and time the process exited. OPTIONS
The following options are supported: -f file Uses file as the source of accounting data. file may be either an extended process accounting file or a standard process accounting file. -x Uses the currently active extended process accounting file. If extended processing accounting is inactive, no output will be produced. EXAMPLES
Example 1: Listing executions of named commands The command example% lastcomm a.out root term/01 produces a listing of all the executions of commands named a.out by user root while using the terminal term/01. Example 2: Listing all user commands The command example% lastcomm root produces a listing of all the commands executed by user root. FILES
