Ok.. I understand I messed up ...

I started clean again .. Below is the script

/usr/local/mano$ cat rpomon.sh


FIRST=`awk 'BEGIN{FS="|";OFS=" "}NR==1{print $1}' /tmp/temp.txt`...

Sorry .. That was typo... The output of the script is blank... This any thing on to the screen

The above gives the following output

rpomon.sh: 21: =0: not found

I presume.. This following is the script you meant by ??

#!/bin/sh

awk 'NR<=2{print $1}' FS='|' OFS=' ' /tmp/temp.txt |read FIRST SECOND
echo $FRIST
echo $SECOND
ress=$(( FIRST + SECOND ))...

#!bin/ksh
> awk 'NR<=2{print $1}' FS='|' ORS=' ' kk |read FIRST SECOND
> ress=$(( FIRST + SECOND ))
> echo $res

I tried this .. the output is as follows

1226048503l
1226048462l
rpomon.sh:...

Thank you very much for you time..

First script executes with out any error, but in the output just blank line.

Second script throws the following error

"rpomon.sh: 14: let: not found"
...

Im not able to perform arthematic operation on these ..

FRIST VALUE IS 1226045443l
SECOND VALUE IS 1226045402l

Error Im getting

expr: non-numeric argument


my code

str= `expr...

OK I got it

FRIST=`echo | awk 'NR==1 {print;exit}' /tmp/temp.txt`
echo $FRIST
SECOND=`echo | awk 'NR==2 {print;exit}' /tmp/temp.txt`
echo $SECOND


But Can I convert these variables to...

while read -r LINE
do
if [ $start=0 ];
then
FRIST=`echo $LINE | awk -F"|" 'NR==1''{print $1}'`
echo $FRIST
SECOND=`echo $LINE | awk -F"|" 'NR==2''{print $1}'`
echo $SECOND
fi
done <...
