want to exit after tail command in unix

Question

I am using shell scripts , which performs following command

hadoop fs -cat /input-path/* | grep "text" | tail -1

I want to exit after this command, so that my shell scripts will execute another command.

Solution

You can use this sed instead to exit as soon as text is found:

sed '/text/q' <(hadoop fs -cat /input-path/*)

it's exiting now , but grep is not working properly.

Even awk '/text/{print; exit}' <(hadoop fs -cat /input-path/*) also works.
