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?
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. TypingC-ssearches 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
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
For KDE's terminal app (Konsole), you can disable flow control with XON/XOFF from settings according to THIS answer:
"in Konsole you can disable this feature, by going to Settings -> Configure Profile -> Choose current profile -> Edit Profile -> Advanced Tab and disable 'Enable flow control using Ctrl+S and Ctrl+Q'"
