I am a huge fan of this magic in my .inputrc which allow me to quickly autocomplete a command with the up arrow key.

"\e[A": history-search-backward
"\e[B": history-search-forward
"\eOA": history-search-backward
"\eOB": history-search-forward

However very often, I have to ssh on a vanilla linux where I have to use CTRL+R. I then usually became very unproductive because I don't know how to use this command.

It is time to question my workflow. Can I be more productive by using the native bash history reverse search than my .inputrc magic?

Concrete use case

I would like to recall the last python line I have written. With my solution I do pyt+ + Enter

With the reverse-i-search, if I do CTRL + R, pyt. I usually get any command containing pyt, not the last command starting with python.

More annoying, I usually realize I should use my history when I already typed let's say pyth. If I hit CTRL + R I get:

(reverse-i-search)`': pyth

Which is very confusing because if I type o I suddenly get a WTF command I typed ages ago containing just a o.

I am totally sure I am not using the reverse-i-search the right way. What am I missing?

Are you using additional CTRL + R keystrokes to go beyond the first match?

In your example above, when you hit pyth you can then continue matching further back with additional CTRL + R presses.

Is that what you were looking for?


Update: Added example below, as requested.

Example: I want to match the older of these two similar commands.

$ python -m this
# ... snip...

$ python -c "import this"
# ... snip...

Now when you:

  1. CTRL + R
  2. Start typing pyt

At this point you have matched the latter of the two commands. Not the one you want (in this example).

  1. Hit CTRL + R one more time

At this point you will be matching the command you desire.

  • @nowax, If that is not what you were looking for, then maybe you could clarify and I'll see what I can do. Best of luck. – Guy Hoozdis Mar 4 at 21:40
