In other words, surround match with single quote marks (') to prevent shell interpolation of wildcard chars like '*'
Code:
find . -name 'Ubuntu*'
which matches names that start with Ubuntu and in exact case sensitivity.
Case in-sensitive uses '-iname' instead of '-name'
The man page is pretty comprehensive eg
https://linux.die.net/man/1/find ; loads(!) of options for tweaking the find cmd.
