Listing content from two directories with wildcard
I have a task to list all files from /bin and /usr/bin that contain an e that is neither at the beginning nor at the end.
The wildcard is [!e]*e*[!e] and works.
(Tested commands cd /bin & ls -l [!e]*e*[!e]
The problem is I have to print the contents of both directories using this wildcard in one command. How do I do that?

Oh sure your version works I forgot that the wildcard specifies a relative path. Thank you!

You could boil it down to one command and one (typed) argument:
ls -d {/usr,}/bin/[^e]*e*[^e]
I added -d in case there to be subdirectories matching the pattern. That expands in phases to:
/usr/bin/[^e]*e*[^e]and/bin/[^e]*e*[^e]
after expanding the braces.
The [^e] requires something other than an e, followed by * anything, followed by an e, followed by * anything, followed by another non-e (followed implicitly by nothing -- indicating the end of the filename).

Looks very interesting but it says: ls: cannot access '/usr/bin/[!e]*e*[!e]': No such file or directory & ls: cannot access '/bin/[!e]*e*[!e]': No such file or directory
