Merge 295fe153ad into 2028f6cb09

Hello, I've added a small blockquote below the description to indicate that this method of accessing an indefinite number of function arguments has been superseded by the use of the spread operator via rest parameters for ES6+ compatibility.

+# List All Fonts On Your Machine
+
+In trying to figure out what _FiraCode_ font I have installed on my machine
+and what it is called, I came across [this StackOverflow
+answer](https://stackoverflow.com/a/52789662/535590) which shares the
+following one-liner:
+
+```bash
+$ fc-list | awk '{$1=""}1' | cut -d: -f1 | sort | uniq
+```
+
+This uses `fc-list` to get the names of all the fonts available on your
+machine. This seems to work on both Linux and Mac. Through a series of `awk`,
+`cut`, and `sort | uniq`, this command produces a clean, easily-browsed list
+of fonts.
+
+I like to take this a step further by piping it all to `fzf` where I can then
+narrow down the output to just lines that match _FiraCode_.
+
+```bash
+$ fc-list | awk '{$1=""}1' | cut -d: -f1 | sort | uniq | fzf
+```
