- | Call me pernickety, but when I use ls, I prefer my files listed vertically not horizontally. Most of the time anyway. ls -1 lists vertically, one file or folder per line. (I’m salivating as I write.); but I don’t want to write ls -1 each time. So what can I do? Use the alias function. It's very simple, and also on the LPIC 1 Exam 101 syllabus.* alias forms new commands or modifies existing commands, the latter relevant here. But first: which aliases (aliai?) already exist? | + | ===== 1 ===== |

But wait! It's not enough. I want to have my nand2tetris folder (very cool little learning project) at the top of that list. In fact, I always want my folders listed first. A quick consultation under ls --help informs me that ls --group-directories-first will get the job done. I can have all I would have hoped (and still do ever hope) for. If only I wouldn’t have to type that pesky addendum to each ls command: --group-directories-first. | But wait! It's not enough.
