[SOLVED] Name independent toggle

I write a bash script for toggle conky

#!/bin/bash

if ! pgrep conky >/dev/null; then
    echo "Turning conky ON"
    conky &
else
    echo "Turning conky OFF"
    pkill conky
fi

exit 0

If I name this script conky_toggle.sh and run then "pgrep conky" will always return 0 like conky already run.
How to write this kind of scripts correct? What can replace pgrep and pkill?

pgerp -x, pkill -x.
Or write C daemon program which will save process id of runned conky and toggle.

Instead of pgrep, use pidof with a full path:

pidof /usr/bin/conky

Or busybox's version doesn't need a full path but matches the full name:

/usr/lib/initcpio/busybox pidof conky

This is particularly useful for python programs (e.g., qutebrowser) as coreutils' pidof will not match their names or full path at all.
