find all active IP addresses in a network

Use the following variation for FreeBSD: $ openssl rand 6 | xxd -p | sed 's/\(..\)/\1:/g; s/:$//'

Which processes are listening on a specific port (e.g. port 80)
swap out "80" for your port of interest. Can use port number or named ports e.g. "http"

Tweak system files without invoking a root shell
only for sudo-style systems. Use this construct instead of I/O re-directors ``>'' or ``>>'' because sudo only elevates the commands and *not* the re-directors. ***warning: remember that the `tee` command will clobber file contents unless it is given the ``-a'' argument Also, for extra security, the "left" command is still run unprivileged.
