Save memory and typing when arrow searching through history

echo '\n"\e[A": history-search-backward\n"\e[B": history-search-forward\n"\e[C": forward-char\n"\e[D": backward-char\n' >> ~/.inputrc
Appends 4 configuration lines to your ~/.inputrc which allow you to seach history taking into account the characters you have typed so far. It is taken straight form https://help.ubuntu.com/community/UsingTheTerminal Go there for a complete description (grep for "Incremental history searching"). Not sure about the limits of this (which OS's/terminals), but probably anything unix/linux like will do. Changed my life :)
Sample Output
### Start typing a command, say "nm", 
$ nm      # Realize you've done this before, so just press up arrow
$ nm /usr/bin/wine       # Bash completes from history ignoring anything not starting with "nm"
### Not the one you wanted? Just keep hitting up arrow until you find the one you want.
$ nm /usr/bin/wineserver
### Hit down arrow to go back.
$ nm /usr/bin/wine      # This is like normal up and down arrows but taking first characters into account.
### Need to be more specific? Note that the cursor is still after the "nm" that we typed at first, so if we hit "a" it shows this:
$ nma /usr/bin/wineserver
### ...but then, another press of up/down arrows and, voila, we get:
$ nmap -sUT -p- localhost
### Just go ahead and hit enter (you don't need to be at the end of the line) and it runs:
Starting Nmap 7.21 ( http://nmap.org ) at 2020-02-29 09:20 XGT

What do you think?

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
