Since your question is specific about bash:
To set it permanently for every new session:
echo 'set -o vi' >> ~/.bashrc
or (recommended), add (or change) a line in ./inputrc:
set editing-mode vi
This will set the editing mode of readline which is used by several other programs beside bash.
It is easy to unset both options:
shopt -ou vi emacs
To set one, either:
set -o vi
Or
shopt -os vi
The same for emacs
. Setting vi
unsets emacs
and viceversa.
To list the state:
$ shopt -op emacs
set +o emacs
$ shopt -op vi
set -o vi
Or both at once:
$ shopt -op emacs vi
set +o emacs
set -o vi
To test if vi
is set:
shopt -oq vi && echo vi is set
Or (ksh syntax):
[[ -o vi ]] && echo vi is set
emacs:
shopt -oq emacs && echo emacs is set
Or:
[[ -o emacs ]] && echo emacs is set
or, to test that no option is set:
! ( shopt -oq emacs || shopt -oq vi ) && echo no option is set

To set
:
set -o vi
Or:
set -o emacs
(setting one unsets the other. You can do set -o vi +o vi
to unset both)
To check:
if [[ -o emacs ]]; then
echo emacs mode
elif [[ -o vi ]]; then
echo vi mode
else
echo neither
fi
That syntax comes from ksh
. The set -o vi
is POSIX. set -o emacs
is not (as Richard Stallman objected to the emacs
mode being specified by POSIX) but very common among shell implementations. Some shells support extra editing modes. [[ -o option ]]
is not POSIX, but supported by ksh, bash and zsh. [ -o option ]
is supported by bash
, ksh
and yash
(note that -o
is also a binary OR operator for [
).
It works and it is surprising, that it is that difficult to determine the mode.

set -o | egrep -w '^emacs|vi'
will return whether emacs or vi is set.

There is also bind -V | grep editing-mode
.
man bash
is huge but well worth reading in depth.
