Bash Shell Error

[lokeshrajoria]

Hello Everyone,

Please go through this script code .
this script files executing in bash 2.05 version without mentioning sh. That means if I type simple in command prompt :
$moverds.sh
then it is execution without any problem and when I try to execute by type in command prompt like:
$sh moverds.sh then
its giving the following Error

[e-mail] # sh moverds.sh
+ read Line
+ ls /test
moverds.sh: bad substitution
[e-mail] #

CODE:
#!/bin/sh
set -x
ls /test | while read Line
do
rds=${Line%_*}
ls | find $rds
if [ $? -eq 0 -a -d $rds ] ; then
if cp /test/$Line /$rds
then
echo "file:$Line : has been transfered to :$rds folder...."
else
echo "file:$Line : has not been transfered to :$rds folder...."
fi
else
if [ -f $rds ] ; then
rm $rds
fi
mkdir $rds
if cp /test/$Line /$rds
then
echo "file:$Line : has been transfered to :$rds folder...."
else
echo "file:$Line : has not been transfered to :$rds folder...."
fi
fi
done

Thank's & Regard's
