How to store multiple outputs from an awk command?
Code:
x=`echo $line | awk -F "|" '{print $1;print NR}'`

How will I get the 2 return values ($1 and NR) from awk to variables?

I'm sure there are a million ways to do it, here's one...

Code:
x1=`echo $line | awk -F "|" '{print $1}'`
xNR=`echo $line | awk -F "|" '{print NR}'`

If xNR is a big value, how to store the actual value instead of in exponential terms?

Some more ways with only one awk:

ksh
Code:
echo $line |  awk -F "|" '{print $1; print NR}' | xargs | read x1 x2

Code:
echo $line |  awk -F "|" '{print $1,NR}' | read x1 x2

-or-
Use an array:
Code:
X=( $(awk -F "|" '{print $1,NR}' <<<$line ) )
echo ${X[0]} 
echo ${X[1]}

bash/ksh
Code:
read x1 x2 < <(echo $line |  awk -F "|" '{print $1,NR}'

)
Code:
read x1 x2 < <(awk -F "|" '{print $1,NR}' <<<$line)

bash/ksh/posix:
Code:
echo $line |  awk -F "|" '{print $1,NR}' |{ read x1 x2
echo $x1
echo $x2
}

Code:
set -- $(echo $line | awk -F "|" '{print $1,NR}')
x1=$1
x2=$2

-or-
Code:
x1="${line%%|*}"; x2=1
