Hi,
it seems `lastcomm' doesn't filter if it gets arguments
or am I reading wrongly man page?

>From man page:
~~~
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.
