read_string

String read_string(File)

Reads an entire file as a String, with any trailing end-of-line characters (\r and \n) stripped off. If the file is empty, an empty string is returned.

If the file contains any internal newline characters, they are left in tact.

Parameters

1. File: Path of the file to read.

Returns: A String.

    # s will contain "this\nfile\nhas\nfive\nlines"
    String s = read_string(stdout())
