I started working on bioinformatics a few years ago (recently switched to cloud computing), 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. Not all the code here is oneliner, but i put effort on making them brief and swift. I am mainly using Ubuntu, RedHat and Linux Mint and CentOS.
This note will focus on simple bash commands for parsing data and Linux system maintenance that i acquired from work and LPIC(Linux Professional Institute Certifications ) exam. I apologize that there are no detailed citation for all the commands, but they are probably from dear Google and Stackoverflow.
I wish to share all my notes with you.
