hi, maybe you can use the -A an d -B option of grep, i put and example :
texto= is a file for example, has 6lines
man grep:
-A NUM, --after-context=NUM
Print NUM lines of trailing context after matching lines.
Places a line containing -- between contiguous groups of
matches.
-B NUM, --before-context=NUM
Print NUM lines of leading context before matching lines.
Places a line containing -- between contiguous groups of
matches.

Code:
$more texto
line1
line2
line3
line4
line5
line6
$grep -A 2 -B 1 "line3" texto
line2
line3
line4
line5
$grep -A 1 -B 2 "line3" texto
line1
line2
line3
line4
