Peek into any file right from your terminal.
Just run piek yourfile.txt from anywhere in your terminal to open the file.
Use your arrow keys (up and down) to navigate from within the file. You can also
expand/collapse the size of your view by pressing shift+up/down.

You need Node.js installed. Run npm i -g piek to install PIEK globally so you can run
piek filename.txt from anywhere in your terminal.
$ npm i -g piek
$ piek filename.txt
You can also run PIEK by calling npx piek yourfile.txt to skip installation and directly
run it.
$ npx piek yourfile.txt
