# Introduction | |
fzf is a powerful tool to interactively select a line among data piped | |
to stdin, a simple example is to pick a line in your shell history and | |
it's my main fzf use. | |
fzf ships with bindings for bash, zsh or fish but doesn't provide | |
anything for ksh, OpenBSD default shell. I found a way to run it with | |
Ctrl+R but it comes with a limitation! | |
This setup will run fzf for looking a history line with Ctrl+R and will | |
run it without allowing you to edit the line! /!\ | |
# Configuration | |
In your interactive shell configuration file (should be the one set in | |
$ENV), add the following function and binding, it will rebind Ctrl+R to | |
fzf-histo function that will look into your shell history. | |
``` | |
function fzf-histo { | |
RES=$(fzf --tac --no-sort -e < $HISTFILE) | |
test -n "$RES" || exit 0 | |
eval "$RES" | |
} | |
bind -m ^R=fzf-histo^J | |
``` | |
Reload your file or start a new shell, Ctrl+R should now run fzf for a | |
more powerful history search. Don't forget to install fzf package. |
