🐧 Rofi: a window switcher, application launcher and dmenu replacement

Rofi is a window switcher, application launcher and dmenu replacement.

I’ve been using rofi with i3-gaps since early 2019. I had played with it before, but I’ve been using it daily the last couple of years.

I use it to launch applications, open ssh sessions, with pass and with a set of useful custom scripts.


You need to install the rofi package. I also installed rofi-dmenu for dmenu compatibility, rofi-pass to use with pass and the extra rofi-emoji and rofi-calc.

paru -S rofi rofi-dmenu rofi-pass rofi-emoji rofi-calc


You can run Rofi in different modes depending if you want to launch an application, open a ssh session, change windows or executing a command in the terminal.

Check Rofi at github and man rofi for more details.

In my setup, and using i3-gaps (learn more here) I use it to accomplish a series of tasks:

bindsym    $mod+d     exec --no-startup-id "rofi -modi combi -show combi -combi-modi drun,run"


bindsym    $mod+p    exec --no-startup-id rofi-pass


bindsym    $mod+s    exec --no-startup-id rofi -show ssh
bindsym    $mod+f    exec --no-startup-id websearch


Here’s my websearch script, inspired by ditrotube.

cat .local/bin/websearch

#!/usr/bin/env bash


declare -a options=(
"searx - https://searx.tuxcloud.net/?q="

"reddit - https://www.reddit.com/search/?q="

while [ -z "$engine" ]; do
  enginelist=$(printf '%s\n' "${options[@]}" | rofi -dmenu -p 'Choose search engine:') || exit
  engineurl=$(echo "$enginelist" | awk '{print $NF}')
  engine=$(echo "$enginelist" | awk '{print $1}')

while [ -z "$query" ]; do
  if [[ "$engine" == "quit" ]]; then
    echo "Program terminated." && exit 0
    query=$(echo "$engine" | rofi -dmenu -p 'Enter search query:') || exit

$DMBROWSER "$engineurl""$query"



The rofi configuration file is located at .config/rofi/config.rasi.

cat .config/rofi/config.rasi

configuration {
    modi:                   "run,ssh,window,combi,drun,windowcd";
    matching:               "fuzzy";
    show-icons:             true;
    theme:                  "~/.config/rofi/themes/dmenu.rasi";
    font:                   "Cantarell Regular 11";
    icon-theme:             "oomox-gruvbox-dark";
    lines:                  7;
    separator-style:        "solid";
    hide-scrollbar:         true;
    kb-row-down:            "Control+j";
    kb-row-up:              "Control+k";
    kb-accept-entry:        "Return,KP_Enter";
    kb-remove-to-eol:       "";
    display-drun:           "Open";
    display-run:            "❯ sh";
    display-combi:          "";
    display-window:         "Change window";
    display-windowcd:       "Change window (same workspace)";
    terminal:               "/usr/bin/alacritty";
    ssh-command:            "{terminal} -e {ssh-client} {host}";

I’m using a theme to emulate dmenu, but I used a gruvbox inspired on until recently.
