A small script to toggle Mute for Dwm Freebsd 13

 this is my small script just to toggle mute in mixer.

I name the script "togglevol.sh"

$>chmod +x togglevol.sh

$>sudo cp togglevol.sh /usr/bin/

and bind it with any key you want in Dwm.

#!/bin/sh


FILEPATH=~/.togglevol
CURRVOL=`mixer vol | awk '{print $NF}'`

## DEBUG
#echo "mixer vol: $CURRVOL"

if [ $CURRVOL = "0:0" ]; then
  ## return the value from file
  FILEVOL=`cat $FILEPATH`

  mixer vol $FILEVOL

else
  ## save current value to file
    echo "$CURRVOL" > $FILEPATH

    mixer vol 0:0
fi
