Cheat Sheet of UNIX commands for Data Science I was looking for a cheat sheet of UNIX commands, which are specifically usable for data science. I mean an introduction to very basic commands (starting from cd, ls, pwd, to some still simple but usable for data - e.g. wc, a few simple things with pipes, ssh, maybe s3cmd, etc), with some minimalistic examples.

I couldn't find one; or at least, nothing close to:


Git Cheat Sheet
Regular Expressions Cheat Sheet
series of R Cheat Sheets


I am pretty much aware of datascienceatthecommandline.com, but my goal would be to have a 1-2 A4 pages printout, with really simple stuff.

If there is one (but I missed it), I would be grateful for posting it as an answer. If there isn't, then I am asking to post pieces of such list.

(If Moderator permits, we may create one list with Community Wiki.)

EDIT: The closest thing I've found is here: Useful Unix commands for data science (very nice, but missing the very introductory part).
I would recommend this one - http://www.cheat-sheets.org/saved-copy/ubunturef.pdf

Its comprehensive, but not data science specific. 

There are a number of great cheat sheets here that may be what you are looking for:https://dzone.com/refcardz
