Shell script is:

IN=$1
c=`echo $IN | tr -dc ';' | wc -c`
b=(`awk -F';' '$1=$1' <<<$IN`)
i=0
while [ $i -le $c ];
do
d=(`echo ${b[i]} | tr '-' ' '`)
a=${d[0]}
b=${d[1]}

while [ $a -le $b ];
do
echo $a
a=`expr $a + 1`
done
i=`expr $i + 1`
done




The input that has to be given in text entry should be in the format 
"1-10;20-30;40-50;60-70"

and this will be passed to shell script and it gets splitted there and the numbers from 1-10,20-30,40-50,60-70 (as per the given input) will be displayed.
The shell script alone is working fine, but if I give more inputs through the text entry then it's not getting passed form Gtk program to shell program
