grep with pattern and line number
 

Hi,

I want to grep the patteren that starts with some name. if it matches then print next 7 lines.

Working fine if i use the below syntax
# grep -A 7 app /tmp/wiki

Not working if i grep the pattern that starts with
# grep -A 7 "^app" /tmp/wiki
# echo $?
1


Can any body help to correct the syntax to find the pattern that starts with or any alter command ?

No issue found with the syntax. it was fine but the file was not having anything that starts with the word "app"
