Unable to forward search Bash history similarly as with CTRL-r
BashSearchBash Problem Overview
I am trying to search my bash history similarly as with CTRL-r, but to forward direction.
It has been a pain for me, when I just hit once too often CTRL-r, to find the previous command again.
How can you forward search your Bash history similarly as in reverse searching?
Bash Solutions
Solution 1 - Bash
You can search forward as well. From the bash info manual, "8.2.5 Searching for Commands in the History":
>To search backward in the history for a particular string, type C-r
.
>Typing C-s
searches forward through the history.
The problem with Ctrl-S however is that sometimes collides with XON/XOFF flow control (in Konsole for instance). The searching is a readline feature however, and you should be able to bind it to some other key. Update: Simpler and better is just to disable XON/XOFF by running
stty -ixon
Solution 2 - Bash
The best trick IMHO is enabling with pgup
and pgdown
. just put that in your ~/.inputrc
"\e[5~": history-search-forward
"\e[6~": history-search-backward
logout/login, type the first letters and then pgup
or pgdown
to search throughout history
ctrl-R
search all lines containing words, whereas history-search-forward search lines beginning with words
Solution 3 - Bash
You may want to try https://github.com/dvorka/hstr which allows for "suggest box style" filtering of Bash history with (optional) metrics based ordering i.e. it is much more efficient and faster in both forward and backward directions:
It can be easily bound to Ctrl-r and/or Ctrl-s
Solution 4 - Bash
I usually press ESC in terminal, and then the >. It resets at least and then you could try click less too often CTRL+R.
Solution 5 - Bash
Another solution is to use:
history | grep <searched expression>
Solution 6 - Bash
As many have experienced, ctrl+s freezes (and ctrl+q unfreezes) the terminal because of software flow control (XON/XOFF flow control) and you can disable it as mentioned in the accepted answer.
Although I can't say I've really intentionally used the feature, I do want the option to be able to pause a fast moving stream of terminal text, so I didn't want to completely disable it.
So instead of turning it off, I rebound the xoff function by placing the following in my .bashrc
stty stop '^P'
Which binds xoff to ctrl+p (and ctrl+q still unfreezes). I used "p" for "pause" and this does obscure the bash previous command function previous-history
. Personally I always use the up arrow key for that so it doesn't matter to me, but you could choose a different key.
This automatically frees up ctrl+s for forward-search-history
