Reading filenames into an array

Question

I want to get a list of files and then read the results into an array where each array element corresponds to a file name. Is this possible?

Answer 1

Don't use ls, it's not intended for this purpose. Use globbing.

shopt -s nullglob
array=(*)
array2=(file*)
array3=(dir/*)

The nullglob option causes the array to be empty if there are no matches.
