How to open and read a file in one line in ruby

Question

How would this be written to be on a single line?

in_file = open(from_file)
indata = in_file.read

indata = File.open(from_file).read. from_file - path to file — Ilya, Apr 01 '16 at 15:42

"How would this be written to be on a single line?" – Use semicolon instead of newline. Always works, you can write *any* Ruby program, no matter how complex, in one single line. — Jörg W Mittag, Apr 01 '16 at 23:32

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.
