Question

I have a script which uses grep to output like this:

12 Apples
10 Grapes
11 Mangoes

I want to the output as

Apples: 12 Grapes: 10 Mangoes: 11

How to modify the grep output?

Answer 1

You could pipe to awk like:

$ echo "
12 Apples
10 Grapes
11 Mangoes
" | awk 'BEGIN { OFS=": "; ORS=" "; } NF >= 2 { print $2, $1; }'
Apples: 12 Grapes: 10 Mangoes: 11 

replacing, of course, the echo cmd with the grep you are doing.
