Top Forums Shell Programming and Scripting Nested if statements with word/number extracts Post 302901401 by Corona688 on Tuesday 13th of May 2014 04:00:36 PM

grep, like all shell utilities, returns a code if it succeeds or fails. You don't need to count the number of lines it prints to tell whether it found anything. You can feed it directly into an if-statement and use less processes for the same result.

Code:
if grep "string" filename >/dev/null
then
        echo "string found in filename"
else
        echo "string not found in filename"
fi
