Installation

__fzf_historial() {
echo " "
echo -ne "\033[2;H"
local histfile="${HISTFILE:-$HOME/.bash_history}"
[[ ! -f "$histfile" ]] && return
local lang="${LANG:-en}"
local titulo prompt
if [[ "$lang" =~ ^es ]]; then
titulo="Historial de comandos"
prompt="Comando ▶ "
else
titulo="Command history"
prompt="Command ▶ "
fi
local cmd
cmd=$(awk '{ l[NR]=$0 } END { for (i=NR;i>0;i--) print l[i] }' "$histfile" \
| grep -v '^#' | grep -v '^$' \
| fzf \
--height=50% \
--layout=default \
--border=rounded \
--cycle \
--border-label="] $titulo [" \
--preview='echo {}' \
--preview-window=down:0:hidden \
--margin=1,35% \
--color='border:2,label:6:bold,bg+:1,fg+:15:bold,pointer:6:bold,marker:2:bold,prompt:6:bold' \
--pointer='▶ ' \
--marker='▶ ' \
--prompt="$prompt")
[[ -n "$cmd" ]] && READLINE_LINE="$cmd" && READLINE_POINT="${#cmd}"
}
bind -x '"\C-r": __fzf_historial'
- Apply the changes with:
source ~/.bashrc
Usage
Press Ctrl-R in your Bash prompt.
An interactive history menu will appear. Once you choose a command, it will be inserted directly into the prompt so you can edit or run it.
Note
This method does not auto-execute the selected command. It gives you the chance to review and modify it first.
