LASTCOMM(1) FreeBSD 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. The options are as follows: -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: o Name of the user who ran the process. o Flags, as accumulated by the system's accounting facilities. o Command name under which the process was called. o Amount of CPU time used by the process (in seconds). o Time the process started. o Elapsed time of the process. The flags are encoded as follows: B The command executed an indirect branch to a location that did not start with a `BTI' instruction, and terminated with signal SIGILL, code ILL_BTCFI. D The command terminated with the generation of a core file. F The command ran after a fork, but without a following execve(2). M The command did a system call from writable memory or the stack pointer was not in stack memory. P The command was terminated due to a pledge(2) violation. S The command tried to execute a system call from the wrong system call instruction, see pinsyscalls(2). T The command did a memory access violation detected by a processor trap. U The command tried a file access that was prevented by unveil(2). X The command was terminated with a signal.
