+# List Stats For A File
+
+The `ls` command is good for listing files. Tacking on the `-la` flags gives
+you a bunch of info about each of the listed files. To get even more info,
+we can use the `stat` command.
+
+```bash
+$ stat README.md
+16777220 143994676 -rw-r--r-- 1 jbranchaud staff 0 53557 "Jul 14 14:53:44 2018" "Jul 10 14:54:39 2018" "Jul 10 14:54:39 2018" "Jul 10 14:54:39 2018" 4096 112 0 README.md
+```
+
+That's definitely more info, but it is unlabeled and a lot to parse. We can
+improve the output with the `-x` flag.
+
+```bash
+$ stat -x README.md
+  File: "README.md"
+  Size: 53557        FileType: Regular File
+  Mode: (0644/-rw-r--r--)         Uid: (  501/jbranchaud)  Gid: (   20/   staff)
+Device: 1,4   Inode: 143994676    Links: 1

+Modify: Tue Jul 10 14:54:39 2018
+Change: Tue Jul 10 14:54:39 2018
+```
+
+See `man stat` for more details.
