To read ONE line you can use File.readline

Given:

cat file
Line 1
Line 2
Line 3
Line 4

In Ruby:

f=File.open("/tmp/file")

p f.readline 
# "Line 1\n"

File.read("/path/to/file")

It will read whole file content and return it as a result.

open("README.md").read

For very small file, this is acceptable.
