Bonnie I-Man Ng:
I was working on bioinformatics a few years ago and was amazed by those single-word bash commands which are much faster than my dull scripts, time saved through learning command-line shortcuts and scripting.
Recent years I am working on cloud computing and I keep recording those useful commands here. Not all of them is oneliner, but I put effort on making them brief and swift. I am mainly using Ubuntu, Amazon Linux, RedHat, Linux Mint, Mac and CentOS, sorry if the commands don’t work on your system.
