Завершение BASH: игнорировать повторяется?

Question

У меня плохая привычка слишком много раз нажимать TAB при использовании терминала. Если какая-либо вызываемая подпрограмма завершения bash является особенно медленной, это приводит к огромному ожиданию, пока терминал показывает мне список завершения 2-3 раза (или сколько раз была нажата клавиша TAB ).

Есть ли способ получить завершение bash, чтобы просто игнорировать повторное нажатие клавиш?

Answer 1

Страница справочника определяет большой набор "переменных", которые можно определить в файле ~/.inputrc для настройки поддерживаемых ключей завершения.

Стратегически назначив правильную клавишу правильной функции, вы, вероятно, получите желаемый эффект. Тем не менее, вы не можете по-настоящему помешать двойной TAB выполнять работу дважды.

Пример файла ~/.inputrc:

C-TAB: complete
TAB: complete-filename

Область проблем на странице руководства гласит следующее:

Completing
   complete (TAB)
          Attempt  to  perform  completion on the text before point.  Bash attempts
          completion treating the text as a variable (if the text begins with $),
          username (if the text begins with ~), hostname (if the text begins with @),
          or command (including aliases and functions) in  turn.   If  none  of
          these produces a match, filename completion is attempted.
   possible-completions (M-?)
          List the possible completions of the text before point.
   insert-completions (M-*)
          Insert all completions of the text before point that would have been
          generated by possible-completions.
   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.
   delete-char-or-list
          Deletes the character under the cursor if not at the beginning or end of
          the line (like delete-char).  If at the end of the line, behaves identi‐
          cally to possible-completions.  This command is unbound by default.
   complete-filename (M-/)
          Attempt filename completion on the text before point.
   possible-filename-completions (C-x /)
          List the possible completions of the text before point, treating it as
          a filename.
   complete-username (M-~)
          Attempt completion on the text before point, treating it as a username.
   possible-username-completions (C-x ~)
          List the possible completions of the text before point, treating it as
          a username.
   complete-variable (M-$)
          Attempt completion on the text before point, treating it as a shell variable.
   possible-variable-completions (C-x $)
          List the possible completions of the text before point, treating it as
          a shell variable.
   complete-hostname (M-@)
          Attempt completion on the text before point, treating it as a hostname.
   possible-hostname-completions (C-x @)
          List the possible completions of the text before point, treating it as
          a hostname.
   complete-command (M-!)
          Attempt  completion  on  the  text  before  point, treating it as a
          command name.  Command completion attempts to match the text against aliases,
          reserved words, shell functions, shell builtins, and finally executable
          filenames, in that order.
   possible-command-completions (C-x !)
          List the possible completions of the text before point, treating it as
          a command name.
   dynamic-complete-history (M-TAB)
          Attempt completion on the text before point, comparing the text against
          lines from the history list for possible completion matches.
   dabbrev-expand
          Attempt menu completion on the text before point, comparing the text
          against lines from the history list for possible completion matches.
   complete-into-braces (M-{)
          Perform filename completion and insert the list of possible completions
          enclosed within braces so the list is available to the shell  (see  Brace
          Expansion above).
