# bash autocomplete.
# usage: complete -F _foo foo
# usage: _foo () { autocomplete "{foo,bar}" } ; complete -F _foo foo
# there are also options like -o nospace. see man for more info.
# from man: The shell function function is executed in the current shell environment. When the function is executed, the first argument ($1) is the name of the command whose arguments are being completed, the second argument ($2) is the word being completed, and the third argument ($3) is the word preceding the word being completed on the current command line. When it finishes, the possible completions are retrieved from the value of the COMPREPLY array variable.
