Sorry @jimcat8
It's toi early in the admin guide for this example.
We did not introduce at this step the regexp, but only the wildcards.
This example would be beter in the advanced commands. Or as an extended example in supplement to the actual one, not to replace.

@jimcat8 I tend to agree with @alemorvan on this. The goal of the admin guide is to gradually step people up in their understanding of commands and syntax. I would suggest that you write either another chapter or a supplemental section to include some more advanced commands that include regexp.

@sspencerwire @alemorvan I am infected with COVID-19, and now it is the fifth day. I don't have the energy to write another tutorial on regular expressions yet.

I hope you are OK @jimcat8.
Let's wait you are better to move forward.
Keep safe.

We can imagine something like this :

* List `/var` files larger than 1 megabyte but less than 1 gigabyte:
ls -lhR /var | grep \- | grep [1-9]*M

Note that it exists something we call "regexp" that permits more advanced search. The regexp will be coverd in the advanced command chapter, but try to understand if you can this advanced sample:

$ ls -lhR /var/ | grep ^\- | grep -E "[1-9]*\.[0-9]*M" 

What do you think about it ?

It should be noted that the files filtered by these two commands are different.
