How to remove files that start with a number and don't end with a letter?

Question

I am doing some practice question off a text book and I ran into one thing that I cannot seem to solve. It wants us to remove all files that

• start with a number and
• end is not a letter

So I use Linux and created a few empty files like this:

>1afsd.
>12fdfd
>12dfad
>23fdfa1
>fdafad!

I tried with this command

rm -i [0-9]

which only removes the ones that have number in it

rm -i *[!a-zA-Z]

which only remove the one that does not have a letter at the end.

Is there a way for it to do both? I tried

rm -i [0-9]* *[!a-zA-Z]

but it's just the same command ran twice. How do I combine them?

Note: I am using the -i so I don't delete the file or I have to recreate them every time.

Answer 1

I think

rm -i [0-9]*[!a-zA-Z]

should work.
