Ok, so I guess since here is HN, everyone is going to say... "Why would you 'modernize' your bash scripts? Isn't the point of scripts to avoid the GUI altogether? GUIs are inefficient, blah blah blah...". And there is a bit of truth in that, but that's not the whole story. (And since I guess I'll be downvoted heavily, I would suggest you to read this block of text before you do.) This blog post is basically about using GUI inputs to get user input. Which means it's an interactive script, and the direct non-GUI equivalent is a TUI. Which means the script is not something that you will be automating for, but more just of a convenient interactive tool. And by definition TUIs are an inferior version of a GUI, for example it usually won't handle terminal size changes, localization, etc... So it makes plenty of sense to make that a GUI for the sake of having a better input. (And I won't call that 'modernization', but it's a better option than presenting a calendar UI from your bash script or having me input a unix timestamp or something else.) So then you might say that hey the command line equivalent of that GUI input is flags, not interactive input, but well you can make a CLI that gets it's parameters from flags and gracefully fallback to interactive input if you don't have sufficient information. (And no, TUIs are not more efficient than GUIs. CLIs might be, because of shell piping and it's automation techniques. But TUIs are inferior, full stop.)
