This will only check if one of the conditions is true, but not which one is true. If you want to find out, which of the expression is true, you will need to check them one by one..

Which means something like this:
Code:
if (( dm > 0 || cl == 100 || ad == 0 || me > 8 || cp > 0 )); then
  if (( dm > 0 )); then
    echo "dm > 0 "
  fi
  if (( cl == 100 )); then
    echo "cl == 100 "
  fi
   if (( ad == 0 )); then
    echo "ad == 100"
  fi
  if (( me > 8 )); then
    echo "me > 8 "
  fi
  if (( cp > 0 )); then
    echo "cp > 0 "
  fi
else
  echo "None of the conditions are true"
fi

For a shorthand way, you could try something like this:
Code:
if (( dm > 0 || cl == 100 || ad == 0 || me > 8 || cp > 0 )); then
  (( dm > 0 ))    && echo "dm > 0 "
  (( cl == 100 )) && echo "cl == 100 "
  (( ad == 0 ))   && echo "ad == 100"
  (( me > 8 ))    && echo "me > 8 "
  (( cp > 0 ))    && echo "cp > 0 "
else
  echo "None of the conditions are true"
fi

dzen2-dbar

DBAR(1) 						      General Commands Manual							   DBAR(1)

NAME

       dzen2-dbar - simple gadget that you can use in combination with dzen to display a progressbar.

SYNOPSIS

       dzen2-dbar [-w characters] [-s symbol] [-min minvalue] [-max maxvalue] [-l string] [-nonl]

DESCRIPTION

       dbar is an application that generates semi graphical progress meters, from some values you supply to it.

       See the usage examples for a description of the expected input format.

OPTIONS

       A summary of options is included below.

       -max   Value to be considered 100% (default: 100)

       -min   Value to be considered 0% (default: 0)

       -w     Number of charcaters to be considered 100% in the bar  (default: 25 )

       -s     Symbol represeting the percentage value in the bar (default: =  )

       -l     label to be prepended to the bar (default: '' )

       -nonl  no new line, don't put '0 at the end of the bar	 (default: do print '0)

USAGE EXAMPLES

       Static 0% and 100% mark or single value input:

	      Command: echo 25 | dbar -m 100 -l Sometext
	      Output: Sometext	25% [======		      ]

       If your 100% mark changes dynamically or 2-values input:

	      Command: echo "50 150" | dbar
	      Output: 33% [========		    ]

       If your value range is not between [0, maxval] or 3-values input:

	      Command: echo "50 -25 150" | dbar
	      Output: 43% [===========		    ]

       Dbar was written by Robert Manea.
