# repeat or history for dmenu commands

In shell you can use up/down arrows to access previously run commands. How can I have the similar behavior: $mod + D, then up/down arrows to select comamnd, and maybe edit before re-run the command edit retag close merge delete ## 3 answers Sort by » oldest newest most voted The default for$mod+d currently is dmenu_run which utilizes dmenu for prompting.

In dmenu you can navigate the choises with either Left/Right for the (default) single-lined interface or Up/Down for the multi-line interface (with parameter -l NUMBER_OF_LINES). Tab pulls the selected choice and it can then be edited.

In order to have a history of recent commands you can modify dmenu_run to also save and display previous choices. I use the following script instead of dmenu_run (which I named emenu_run):

#!/bin/sh
cachedir=${XDG_CACHE_HOME:-"$HOME/.cache"}
histsize=50
if [ -d "$cachedir" ]; then cache=$cachedir/emenu
hist=$cachedir/emenu_hist else cache=$HOME/.emenu_cache # if no xdg dir, fall back to dotfile in ~
hist=$HOME/.emenu_cache_hist # if no xdg dir, fall back to dotfile in ~ fi if [ ! -e "$hist" ]; then
touch "$hist" echo foo fi cmd=$(
IFS=:
if stest -dqr -n "$cache"$PATH; then
(tac "$hist" ; stest -flx$PATH | sort -u | tee "$cache" ) | dmenu "$@"
else
(tac "$hist"; cat "$cache") | dmenu "$@" fi ) #echo "$cmd" | ${SHELL:-"/bin/sh"} & i3-msg "exec$cmd"

sed -i -e "/^${cmd}$/d;${histsize}q" "$hist"
echo "$cmd" >> "$hist"


This saves the last 50 choices (edit histsize=50 for more or less) alongside the normal cache file and presents them first in order of recentness. It also uses i3-msg exec … instead of just passing it to a shell, which allows for applications that support it (unfortunatelly not all do) to appear on the workspace on which they were called.

Here's another script, not only assessing recency but also, if an app should be run in the background or in the terminal: https://github.com/manjaro/packages-c...
