Bash one-liners can reduce workload, automate something quickly and put the power of ultimate system control in your hands. Over time, you will likely learn to write more complex one-liners and some of the things you end up writing as a seasoned professional will be nearly in-parsible by a beginner. That said, the Bash command and development language is highly structured - and relatively easy to understand - once you know about the in and outs. It really is like becoming proficient in a foreign language.
