Use bash’s ability to search the command history when repetitively using commands on the command line. Don’t bother hitting the Up key for a 100 times, trying to find that hugely complicated command you typed in two hours ago. Hit Ctrl+R, start typing parts of the command and it’ll appear as you type. Didn’t know this feature yet? Ain’t it cool? Will it save you time? Maybe. Will it save you much aggrevation? Quite probably.
Hotwire is an object-oriented hypershell. It is a shell designed for systems programming (files, processes), and thus it is in the same conceptual category of software as the Unix shell+terminal and Windows PowerShell.
