 `ls` can usually be replaced by `find` if it's just the filenames, or a count of them, that you're after. Note that if you are using `ls` to get at the contents of a directory, a straight substitution of `find` may not yield the same results as `ls`. Here is an example:
 
-```

 You can see two differences here. The first is that the `find` output has the full paths to the found files, relative to the current working directory from which `find` was run whereas `ls` only has the filenames. You may have to adjust your code to not add the directory to the filenames as you process them when moving from `ls` to `find`, or (with GNU find) use `-printf '%P\n'` to print just the filename.
 
 The second difference in the two outputs is that the `find` command includes the searched directory as an entry. This can be eliminated by also using `-mindepth 1` to skip printing the root path, or using a negative name option for the searched directory:
-```
+```console
 $ find .snapshot -maxdepth 1 ! -name .snapshot
 .snapshot/rnapdev1-svm_4_05am_6every4hours.2019-04-02_0005

 **Note:** If the directory argument to `find` is a fully expressed path (`/home/somedir/.snapshot`), then you should use `basename` on the `-name` filter:
 
-```
+```console

 $ find "$theDir" -maxdepth 1 ! -name "$(basename $theDir)"
