Find files and store in array

Find files whose extension is .md and store them in a bash array:

$ mapfile -d $'\0' mds < <(find . -iname '*.md' -print0)

We make use of the mapfile shell builtin with the shell-quoting $'' syntax to specify NUL byte as delimiter (produced by -print0), redirection and process substitution <(...).
