LASTCOMM(1) General Commands Manual LASTCOMM(1)

lastcommshow last commands executed in reverse order

lastcomm [-w] [-f file] [command ...] [user ...] [terminal ...]

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:

file
Read from file rather than the default accounting file.
Use as many columns as needed to print the output instead of limiting it to 80. This is the default behavior on Apple systems.

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 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.

/var/account/acct
Default accounting file.

last(1), sigaction(2), acct(5), core(5)

The lastcomm command appeared in 3.0BSD.
