One could easily find dozens of reasons for which UNIX — mainly Ubuntu — is simply, the best operating system. Although I remember people in my proximity mentioning this for ages, it’s been only a few months that I’ve realized what are the true advantages. Helpful for this were all the people teaching/demonstrating in various modules during my first year in SABS/DTC: quite often we would be asked to do something in the console rather than by clicking the mouse. In the meanwhile, I’d wonder why using the console can be better from a nice, user-friendly GUI (i.e. Windows…). Tools like sed, grep, tar and of course alias-ing form a quick answer. I will not argue more about these but demonstrate two more tools/tricks.
