how to read rows?

Question

I'm trying to read first row from the file

> source ./rank file

using this script

set line = ($<)  <- inside rank

but when I enter

echo $line I receive nothing, how can I change it? thanks in advance

Answer 1

It's built-in in Bash as:

read -r line < filename

Answer 2

Since csh is brain-dead, you'll have to do something like this:

set line = `head -n 1 filename`
