Question

I have implimented a function that searches a column in a file for a string and it works well. What I would like to know how do I modify it to search all the columns fr a string?

awk -v s=$1 -v c=$2 '$c ~ s { print $0 }' $3

Thanks

If “all the columns” means “the entire file” then:

grep $string $file
