this scripts just apply this command for this directory, not for all regular files inside directory. I think that it's needed to use "loop"...

I know that ls -l command will print all information of the files in current directory,but i only want to get the list name of the files (by line).
I try that:

Code:

ls -l | cut -f 9 -d ' '

but, in many cases, it's wrong

Code:

find . -type f

but this command does not show the name of subdirectory(

Code:

 find . -type d

this include the main directory
