• [Linux常用命令]bind


    bind
     1        bind [-m keymap] [-lpsvPSV]
     2        bind [-m keymap] [-q function] [-u function] [-r keyseq]
     3        bind [-m keymap] -f filename
     4        bind [-m keymap] -x keyseq:shell-command
     5        bind [-m keymap] keyseq:function-name
     6        bind readline-command
     7               Display  current  readline key and function bindings, bind a key
     8               sequence to a readline function or  macro,  or  set  a  readline
     9               variable.   Each  non-option  argument  is a command as it would
    10               appear in .inputrc, but each binding or command must  be  passed
    11               as  a  separate argument; e.g., '"\C-x\C-r": re-read-init-file'.
    12               Options, if supplied, have the following meanings:
    13               -m keymap
    14                      Use keymap as the keymap to be affected by the subsequent
    15                      bindings.     Acceptable    keymap   names   are   emacs,
    16                      emacs-standard,  emacs-meta,  emacs-ctlx,  vi,   vi-move,
    17                      vi-command,  and vi-insert.  vi is equivalent to vi-com‐
    18                      mand; emacs is equivalent to emacs-standard.
    19               -l     List the names of all readline functions.
    20               -p     Display readline function names and bindings  in  such  a
    21                      way that they can be re-read.
    22               -P     List current readline function names and bindings.
    23               -s     Display  readline  key  sequences bound to macros and the
    24                      strings they output in such a way that they  can  be  re-
    25                      read.
    26               -S     Display  readline  key  sequences bound to macros and the
    27                      strings they output.
    28               -v     Display readline variable names and values in such a  way
    29                      that they can be re-read.
    30               -V     List current readline variable names and values.
    31               -f filename
    32                      Read key bindings from filename.
    33               -q function
    34                      Query about which keys invoke the named function.
    35               -u function
    36                      Unbind all keys bound to the named function.
    37               -r keyseq
    38                      Remove any current binding for keyseq.
    39               -x keyseq:shell-command
    40                      Cause  shell-command  to  be  executed whenever keyseq is
    41                      entered.  When shell-command is executed, the shell  sets
    42                      the  READLINE_LINE variable to the contents of the rea‐
    43                      line line buffer and the READLINE_POINT variable  to  the
    44                      current location of the insertion point.  If the executed
    45                      command changes the  value  of  READLINE_LINE  or  REA‐
    46                      LINE_POINT,  those  new  values  will be reflected in the
    47                      editing state.
    48 
    49               The return value is 0 unless an unrecognized option is given  or
    50               an error occurred.

     其中keyseq可以使用showkey -a命令来获取,如:

    $ showkey -a
    
    Press any keys - Ctrl-D will terminate this program
