Terminal autocomplete: cycle through suggestions

This is actually a readline feature called menu-complete . You can bind it to tab (replacing the default complete) by running:

bind TAB:menu-complete

You probably want to add that to your ~/.bashrc. Alternatively, you could configure it for all readline completions (not just bash) in ~/.inputrc.

You may also find bind -p (show current bindings, note that shows tab as "\C-i") and bind -l (list all functions that can be bound) useful, as well as the bash manual's line editing section and readline's documentation.

You can cycle through the completion menu in Bash, and you can also show the menu of items. Unlike in Zsh, the current menu item will not be highlighted.

Add to ~/.inputrc:

set show-all-if-ambiguous on
set show-all-if-unmodified on
set menu-complete-display-prefix on
"\t": menu-complete
"\e[Z": menu-complete-backward

Documentation from man bash:

Readline Variables
    menu-complete-display-prefix (Off)
           If set to On, menu completion displays the common prefix of the
           list of possible completions (which may be empty) before cycling
           through the list.
    show-all-if-ambiguous (Off)
           This alters the default behavior of the completion functions. If
           set to On, words which have more than one possible completion
           cause the matches to be listed immediately instead of ringing
           the bell.
    show-all-if-unmodified (Off)
           This alters the default behavior of the completion functions in
           a fashion similar to show-all-if-ambiguous. If set to On, words
           which have more than one possible completion without any
           possible partial completion (the possible completions don't
           share a common prefix) cause the matches to be listed
           immediately instead of ringing the bell.

Completing
    menu-complete
          Similar to complete, but replaces the word to be completed with
          a single match from the list of possible completions. Repeated
          execution of menu-complete steps through the list of possible
          completions, inserting each match in turn. At the end of the list
          of completions, the bell is rung (subject to the setting of
          bell-style) and the original text is restored. An argument of
          n moves n positions forward in the list of matches; a negative
          argument may be used to move backward through the list. This
          command is intended to be bound to TAB, but is unbound by
          default.
    menu-complete-backward
          Identical to menu-complete, but moves backward through the list
          of possible completions, as if menu-complete had been given
          a negative argument. This command is unbound by default.
