I'm using a cache mechanism -- see my dwm-patches[1]:

Step a)
when I start dwm, I remove my cache:

$ rm -f ~/.dmenu-cache

I have this in a small shell script that is called from my login
manager (wdm) and is run automatically. It ends running dwm.

Steb b)
I use the following script called dwm-choose to run dmenu (with
history patch applied):

if [ ! -r "$cachefile" ] ; then
                for dir in $PATH; do
                        for file in "$dir"/*; do
                                [ -x "$file" ] && echo "${file##*/}"
                done | sort | uniq > "$cachefile"
exec $(dmenu -normfg \#bbb -normbg \#000 -selfg \#eee -selbg \#000 -hist "$histfile" < "$cachefile")

This script only scans the $PATH when the history file does not
exist. The first call of dmenu is slow, but subsequent calls are
fast. If I install programs or change my $PATH, I just remove the
cache file manually and the next dmenu call will search the $PATH



If you took all of the grains of sand in the world, and lined
them up end to end in a row, you'd be working for the government!
