 - The `inhere/` indicates that the file whose contents we want to output is in the `inhere` directory.
-- The `.*` is a `glob` matcher, which translates to *cat every file that starts with the character `.` and has an indefinite number of characters after it.* We use it for brevity's sake, as it sidesteps knowing the name of the file inside the `inhere` directory entirely. The only problem is the two error messages output by `cat`, indicating it tried to output the contents of a directory instead of a file.

+- human-readable
+- 1033 bytes in size
+- not executable
+
+We use a new shell utility called `find`, and construct the command as follows
+
+```
+find . -type f -size 1033c ! -executable
+```
+
+The arguments are as follows
+
+- `.` indicates that we want `find` to search in the current directory.
+- `-type f` is to make it so the only results we see are of files `f`. If we wanted to find only directories, we would use `-type d` instead.
+- `! -executable` is a negation of the `-executable` argument, i.e. *"only show files that are \*not\* executable"*
