If you press Tab while using bash in an interactive environment, the list of complementary candidates will be displayed, but is it possible to get this from the shell script?
In other words, the current $PATH and $PWD (or there may be other environment variables) are given strings that are being entered and then the candidates are returned in an array of strings.
Would it be easy to understand if it is close to file-name-all-complets in Emacs LISP?
Please let me know if anyone knows.
