'I already know about recording the Terminal activities using “script” command in Unix-like systems. Today, I found out yet another similar utility called “asciinema” that can used to record Terminal sessions. Forget about the heavy screen-recording tools and/or apps. Asciinema is a fast, light-weight and open source Terminal recording tool. Unlike “script” command, Asciinema not just records our Terminal activities, but also helps us to share them on the web if necessary. You can share the recordings by copying its URL and sending it to a friend or posting it on a social network. It supports Linux, Mac OS X and *BSD.'
