I would like to know value for previous row, in addition to current row.

How would I will get value for previous row? How can I perform this with awk?

what is "value for previous row"?
if you mean "the previous row", just keep saving "rows" in a variable like so:
previous=$0

i prefer grep and sed to solve this problem.

Code:
a=`grep -n "bhargav" file1 | cut -d":" -f 1`
((b=a-1))
if test $b -ne 0
then
sed -n ""$b","$a"p" file1
else
sed -n '1 p' file1
fi
