Display File with a specific letter

Hi im a noob in Unix
Do you guys know what command display you the files that have the character n in there name im not looking that they have the n in the beginning or in the end im looking that in search the entire string to see if it have the character n i try this

ls n*

but only show me the files that begins with n but didnt include the other files that have the letter n but that wasnt in the beging of their names i try to mix the commands

ls n**n

but didnt work and i have to use ls i cant use find but i can mix with grep sandly im still dont understand how to apply grep:(

What about...

ls | grep *n*

No, grep doesn't work that way. Shell globbing does, though. Try ls *n* or find ./ -name '*n*' (find is better when you have hundreds or more matching files).
