Configure terminal history searching

[chrisjsewell]

Just a minor quality of life configuration. I always find it helpful to configure my terminal (a) to not store duplicate commands in history and (b) to allow for incremental searching (e.g. if you type ab, then it will only toggle commands in history beginning with ab.

for (a), you add in ~/.bashrc:

HISTCONTROL=ignoreboth
# optionally increase history capacity
HISTSIZE=1000000
HISTFILESIZE=1000000000

(see https://www.linuxjournal.com/content/using-bash-history-more-efficiently-histcontrol)

for (b), you add in ~/.inputrc:

"\e[A": history-search-backward
"\e[B": history-search-forward

I'm happy to add the history options.
The .inputrc additions, while cool, break CTRL-left and CTRL-right to move the cursor one word to the left and right...

Thinking about it, 1M lines in memory and 1B lines on disk seems a bit excessive... What about 100k for both?

Well I personally find the history much more helpful 😉 but yeh it's not a necessity. Perhaps there's a way to incoporate both

ph yeh sure that was just an example 👍

This appears to do the trick:

"\e[1;5C": forward-word
"\e[1;5D": backward-word

I still want to wait a bit, I might find more stuff that's broken. Cool suggestions though.
