I am trying to use ls and grep. However, I cannot figure out a way to count how many files in the current directory have a name long at least 5 characters.
How can I achieve this?
files grep ls

should files in subfolders be considered?

What have you tried so far? How would you grep for lines with at least five characters?

Simple find + wc commands solution:
find . -maxdepth 1 -type f -name "?????*" | wc -l

If this is homework, the assignment may be looking for something like:
ls | grep ..... | wc -l
Though I would do:
set -- ?????*
echo $#
or
files=(?????*)
echo $#files[@]
Here the important work is done by the shell glob . which says to match one character of a filename; by including 5 of them followed by a * (any number of characters), we generate the list of files with at least 5 characters in them.
The counting is then done by the $# shell parameter in the set solution, or by counting the elements in the array.
