Man bash says
Readline Variables
Readline has variables that can be used to further customize its behav‐
ior. A variable may be set in the inputrc file with a statement of the
form
set variable-name value
or using the bind builtin command (see SHELL BUILTIN COMMANDS below).
That's what I intend to do today. Use the bind command to set a variable.
OK, reading further, none of these
bind [-m keymap] [-lpsvPSVX]
bind [-m keymap] [-q function] [-u function] [-r keyseq]
bind [-m keymap] -f filename
bind [-m keymap] -x keyseq:shell-command
bind [-m keymap] keyseq:function-name
bind [-m keymap] keyseq:readline-command
Show how to set a readline variable.
Display current readline key and function bindings, bind a key
sequence to a readline function or macro, or set a readline
variable. Each non-option argument is a command as it would ap‐
pear in .inputrc, but each binding or command must be passed as
a separate argument; e.g., '"\C-x\C-r": re-read-init-file'. Op‐
tions, if supplied, have the following meanings:
OK, so the syntax is probably one of
$ bind set skip-completed-text on
or
$ bind skip-completed-text off
Yes, even after using
-v Display readline variable names and values in such a way
that they can be re-read.
-V List current readline variable names and values.
it is not clear. (But Junior (me) finally did figure it out below.)
Hmmm,
$ bind -v|wc -l
45
$ bind
Display all 169 possibilities? (y or n)
$ bind set
Display all 169 possibilities? (y or n)
45!=169
$ bind -v|grep skip
set skip-completed-text off
$ bind skip-completed-text on
readline: skip-completed-text: no key sequence terminator
readline: on: no key sequence terminator
$ bind set skip-completed-text on
readline: : unknown variable name
readline: skip-completed-text: no key sequence terminator
readline: on: no key sequence terminator
$ help bind
bind: bind [-lpsvPSVX] [-m keymap] [-f filename] [-q name] [-u name] [-r
keyseq] [-x keyseq:shell-command] [keyseq:readline-function or readline-command]
A glimmer of hope appears. Maybe "name" means variable. (It doesn't. So
really should be written [-q function-name] [-u function-name] as they
are below.)
Set Readline key bindings and variables.
Bind a key sequence to a Readline function or a macro, or set a
Readline variable. The non-option argument syntax is equivalent to
that found in ~/.inputrc, but must be passed as a single argument:
e.g., bind '"\C-x\C-r": re-read-init-file'.
Wait! I see, I need to do
$ bind 'set skip-completed-text on'
$ bind -v|grep skip
set skip-completed-text on
It worked!
Conclusions:
$ bind 'set
should show those 45 completions!
And, the example
bind '"\C-x\C-r": re-read-init-file'
is only for those (169) keys. Please add a second example, for those (45)
variables:
bind 'set skip-completed-text on'
Thanks!
