- Populate an array of the file names and then print how many entries are in the array:
- $ ( shopt -s nullglob; files=( .* * ); echo "${#files[@]}" )
- 124
That will work correctly even if your file names contain newlines, unlike anything piped to `wc -l`. I'm using a subshell to restrict the environment that `shopt -s nullglob` applies to - if you don't care about that then you don't need a subshell.

- Note that the above includes both files and directories (which are, of course, a type of file) - if you want to exclude directories then you need a different solution.

Populate an array of the file names and then print how many entries are in the array:
$ files=( * )
$ echo "${#files[@]}"
124
That will work correctly even if your file names contain newlines, unlike anything piped to `wc -l`.
