When I press the Tab key while using bash in an interactive environment, completion candidates are displayed in a list. Is it possible to get this from a shell script? That is, a function-like image given the current
$PWD (or other environment variables you may need) and the string you are typing, from which the candidates are returned as an array of strings. is.
Is it easy to say that it is close to
file-name-all-completions in Emacs LISP?
If anyone knows, please.
I referred to a similar question in SO.
