After searching google, looking through the bash man page and then looking through the bash source code (the lib/readline/vi_mode.c) it looks like there is no easy way to change the prompt when moving from insert mode to command mode. It looks like there might be an opportunity here for someone to patch the bash source though as there are calls for starting and stopping the modes in the source.

Upon seeing your post it got me interested in the bash vi mode setting. I love vi and would why not on the command line. However it looks like we will have to keep track of whether we are in insert mode without a prompt change (so sayeth many forum posts) For what it is worth you are always in insert mode unless you hit ESC. Makes it a little easier, but not always as intuitive.

I'm upping your question as I'm interested in seeing where this goes.

I try to get a indicator for BASH vi mode also, and you all learned it's sound simple and just no way to do it yet.

My current approach is: hit 'a' when I not sure which mode is. IF 'a' appears after BASH PROMOT, I learn I am in 'INSERT' mode. THEN, I hit 'RETURN' and continue. This is a easy way for me to solve the small annoyance.

By the way, I 'alias a='cal', or something else to give the empty hit 'a' little usefulness.

<pre><code>4. New Features in Readline
j. New user-settable variable, show-mode-in-prompt, adds a characters to the

So putting

<pre><code>set show-mode-in-prompt on

into /etc/inputrc or ~/.inputrc (thx stooj) should affect all your readline-enabled programs ;)

You can try the beta versions, but they seem a bit buggy at the moment. They also don't yet support specifying where in the prompt you want the mode indicator to occur (which I think is the killer feature).

If you don't want to wait, and aren't afraid of a little compilation, I've published patched versions of bash 4.3 and readline 6.3 to github that support this functionality.

With the patched versions you can do stuff like this:

<h1>Different Prompt and Cursor Style via <code>.inputrc</code></h1>

First you should make sure that you're running a bash version higher than <code>4.3</code>:

<pre><code>$ bash --version
GNU bash, version 4.4
</code></pre>

Then put the following lines in your <code>~/.inputrc</code>:

<pre><code>#################### VIM ####################
# FOR MORE INFORMATION CHECK:
# https://wiki.archlinux.org/index.php/Readline

# TURN ON VIM (E.G. FOR READLINE)
set editing-mode vi

# SHOW THE VIM MODE IN THE PROMPT (COMMAND OR INSERT)
set show-mode-in-prompt on

# SET THE MODE STRING AND CURSOR TO INDICATE THE VIM MODE
# FOR THE NUMBER AFTER `\e[`:
# 0: blinking block
# 1: blinking block (default)
# 2: steady block
# 3: blinking underline
# 4: steady underline
# 5: blinking bar (xterm)
# 6: steady bar (xterm)
set vi-ins-mode-string (ins)\1\e[5 q\2
set vi-cmd-mode-string (cmd)\1\e[1 q\2
</code></pre>

In command mode, the cursor is displayed as block. 
In insert mode, the cursor is displayed as vertical bar. 

The prompt itself will then look like this depending on the mode:

<pre><code>(cmd)$ ... 
(ins)$ ...
</code></pre>

When using vi mode (set -o vi) with Bash, it would be nice to have a prompt that depends on the mode you are currently in (insert or command). How does one find out this editing mode?

B.t.w, this seems to be possible in <a href="http://pthree.org/2009/03/28/add-vim-editing-mode-to-your-zsh-prompt/" rel="noreferrer">ZSH</a>:

将vi模式(设置-o vi)与Bash一起使用时，最好能有一个取决于您当前所处模式(插入或命令)的提示符。如何找到这种编辑模式？B.t.w，这在中似乎是可能的
