having problem with a bash script

a few days ago this was working fine but now it will print the song name on the screen and doesn't go away like its supposed to(specified by the ``-d" option for osd_cat). anyone see something wrong? and wth did it work fine a few days ago? also, any general programming tips would be appreciated as this is really the most complicated script lol i've ever had to write.

#!/usr/bin/env bash

#Options:
SCRIPT_DELAY=5
COLOR=black 
POSITION=bottom
OFFSET=-50
MPD_HOST=127.0.0.1
OSD_DURATION=5

#extract just the artist/track name from mpc output
function songname() { mpc | sed '2,3d' ; }

#check if song has changed and break if no. if yes, update MPDSONG and print it on screen
function printsong() {

#if mpc's output is only 1 line,  then mpc is stopped, so don't print anything
if [ `mpc | wc -l` == 1 ]
then return 1

else
   while [ 1 ]
   do
      MPDSONG2=`songname`
      if [ "${MPDSONG}" == "${MPDSONG2}" ]
      then
         break
      else
         MPDSONG=`songname`
         echo $MPDSONG | osd_cat -d "${OSD_DURATION}" -p bottom -c black -u red -O 2 -i 6 --offset="${OFFSET}"
--font=-adobe-helvetica-bold-*-*-*-34-*-*-*-*-*-*-*
      fi
   done
fi
}


while [ 1 ]
do 
   MPDSONG=`songname`
   sleep $SCRIPT_DELAY
   printsong
done

Re: having problem with a bash script

It is working or me. Though I removed to --font argument from the osd_cat command because I don't have the font installed.

The second infinite loop in the function printsong seems a little useless to me.


Hail to the thief!
