Sounds like you've jumped into some deeper bits of linux quite early in your journey ... so all credit to you for that. There's a learning curve that we all had climb, so you are not alone in that.
"fish" is a shell. A shell takes commands from the command line and passes them to the operating system which includes the kernel. When the user inputs a command, the shell returns the output that the command is asking for. The shell is just a program to achieve that output. The main shell in linux has been "bash" for many distributions, but there are plenty of other shells, "fish" being one of them. There's lots online about shells.
To find out what shell you are running, run:
To find out which shells are on your system run:
To change shells, for example to change your login shell to bash run:
Temperature in linux can be obtained from the lm-sensors program. After it's installed, run, as user:
and the output looks like the following, depending on your system of course:
