So i’ve reinstalled my system (KDE) and it used to be that when i typed a partial term and press the up-arrow key, that would browse through all instances of my bash_history that contained that term doesn’t matter where the term was located with the command string, for instance if i would type ‘mesa’ and press up-arrow it would browse through terms like ‘sudo pacman -Ss mesa’, and now up-arrow only browses through commands that begin with the term… what should i do to have that behavior back?
Manjaro KDE uses zsh by default - no idea about how command history completion works there.
In order to use bash in Konsole you have to create a new profile (using bash as the shell), and set it as default.
Just changing the default shell to bash
as in:
chsh -s /bin/bash
will NOT change your shell to bash in Konsole.
A very weird design decision, if you ask me … but no one asked me …

well i don’t understand a lot about the linux shell environment so i’m at loss here 
it is by default using /bin/bash
well - if yours is a recent installation of KDE Plasma
it is definitely not using /bin/bash by default.
check with:
echo $SHELL
and/or
printenv
If you are indeed using bash:
make sure bash completion is installed
otherwise: I don’t know 
it is bash, i just checked…
As I said:
if yours is a recent Manjaro KDE Plasma installation then the shell in the Konsole app is definitely not bash by default.
If it is bash - you actively changed it.
… but what do I know? - I’ll have to believe you
and tell you that I don’t know how to address your issue …
yeah i did change it lol, i keep my config files, well thanks anyways.
