Consider adding pipr

[elkowar]

I think mentioning pipr would be fitting here, as it specifically serves as a really nice and interactive way to play around with shell utilities and pipeline processing commands such as sed, jq, etc in a generic and comfortable way. Of course, note that this is self-promotion (pipr is my project), but stuff like this (specifically also the learning side of this) is part of the reason I made it, so I think it would fit perfectly into here.
