Linux terminal includes myriad of opportunities by default. But sometimes we can’t figure out how to execute any operation easier. From scratch we tried to parse enourmous logs by eyes or use graphical instruments when it’s not necessary. Another problem – we’re forgetting how to type any helpful command we need. Thus there is one way to scroll Google and read the same forum branch we did before. So, it would be better to have a petty prompt with command syntax we really need. It’s useful as on the tab of your document application as well as pinned to the wall in your room.
