Find file with at least one number in /usr/include

Question

Using the find command, I want to see the files in /usr/include whose name contains at least one number.

I tried this command :

find /usr/include -type f -regex '.\*[0-9].\*$'

But the number is not always in the name of the file but sometimes in the path. For example /usr/include/linux/netfilter_ipv4/ipt_ah.h is found.

After that, I tried this command :

find /usr/include -type f -regex '/[^\/]*[0-9][^\/]*$'

But it returns nothing.

How can I resolve this problem?

If you use the -name test instead of the -regex test, it will match only the filename, ignoring the preceding directories (see the man page). Note that -name uses a shell pattern rather than a regex pattern, so the syntax is slightly different. You can use this command to find files which have numbers in the filename:

find /usr/include -type f -name '*[0-9]*'
