Calendar tools, calendar tools. Lots of those to tell about. Of course it all started with cal, a month or so ago.
Here’s a souped-up rendition of that, which goes by a clever name … gcal.
This is a GNU tool, so you’re getting something cleverly powerful and deceptively slim.
gcal by default will give you output that looks a lot like cal’s, but one quick look at its help flags tells you it does much more.
You know, I’d love to go into detail on this one, but I couldn’t do much better than the help manual.
The man pages are a big boost too, if it turns out you do need something with more power than the original cal.
