Hello!
I am writing a bash script, and need to view all files in directory except .cache files and files that do not have any extension.
How to do this?
Thank you!

This will get you started. I'll let you figure out the rest.
find . -maxdepth 1 -type f -name '[!.]*.*' -print

Thank you, but I need to except .cache files:
root@server [/var/cpanel/userdata/username]# find . -maxdepth 1 -type f -name '[!.]*.*' -print
./site.com
./site.com.cache
./main.cache
Another command: ls *.*, but I need to except *.cache.

I left it for you to figure out, since the only way to learn is to do something yourself.
But, since that's not the case and you want me to write it for you.
find . -maxdepth 1 -type f -name '[!.]*.*' -print | grep -v .cache
