My solution work with correction of scrutinizer echo "$s".
Why do you want use FOR loop ?
We use a FOR loop to process a list not a line.
Otherwise, a way to process file line by line with FOR loop:
Code:
OLDIFS=$IFS
IFS='
'
file=/home/dbadmin/jjj.txt
for i in $(<$file)
do
echo "$i"
s=`echo "$i"|tr -s ' ' |cut -d"|" -f1`
q=`echo "$i"|tr -s ' ' |cut -d"|" -f2`
x=`echo "$i"|tr -s ' ' |cut -d"|" -f3`

echo "$s"
echo "$q"
echo "$x"
done
IFS=$OLDIFS

But it's A VERY VERY BAD IDEA to use this.
Regards.
