Disable the ping response
It really disables all ICMP responses not only the ping one. If you want to enable it you can use: $ sudo -s "echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all"

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

I hate `echo X | Y`
apart from not being generalisable to all shells, `Y <<< X` seems nicer to me than `echo X | Y`, e.g. $ <<< lol cat; it reads easier, you type less, and it also looks cool

Get current stable kernel version string from kernel.org
depends on "jq" This is more reliable in my opinion.

Monitor iptables in realtime

Top 10 Memory Processes
It displays the top 10 processes sorted by memory usage

Find usb device in realtime
Using this command you can track a moment when usb device was attached.

Resize a Terminal Window
Replace 70 with the desired height. Replace 180 with the desired width. I put it in my bashrc, because by default my terminal is too small.

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"

Random unsigned integer
works at least in bash. returns integer in range 0-32767. range is not as good, but for lots of cases it's good enough.
