TAB我有一個壞習慣，在使用終端時按太多次。如果任何呼叫的 bash 完成例程特別慢，這會導致長時間等待，而終端會向我顯示完成清單 2-3 次（或無論TAB按下多少次）。
有沒有辦法讓 bash 完成以忽略重複的按鍵？

手冊頁定義了大量“變數”，可以在 ~/.inputrc 檔案中定義這些變數來調整支援的完成鍵。
透過策略性地分配右鍵使用正確的功能，您可能會得到您想要的效果。然而，你無法真正阻止替身重複TAB做同樣的工作。
範例 ~/.inputrc 檔案：
C-TAB: complete
TAB: complete-filename
手冊頁中的關注區域如下：
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).
