Bash bracket expansion: How to match all files names with a number?

问题

I want to match all filenames in a directory that are like this:

h1.txt, h2.txt, h12.txt, h3.txt

If I do

echo h[[:digit:]].txt

I get

h1.txt, h2.txt, h3.txt

so it matches all the files I want, except h12.txt, because it has two digits instead of one. Is there an expansion for one or more digits?

回答1:

Figured it out!

echo h+([[:digit:]]).txt
