LASTCOMM(1) BSD General Commands Manual LASTCOMM(1)NAMElastcomm — show last commands executed in reverse order
SYNOPSISlastcomm [-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.
-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‐
· The command name under which the process was called.
· The amount of cpu time used by the process (in seconds).
· The time the process exited.
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, ``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.
/var/account/acct Default accounting file.
