+# 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
+```
