If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently.
Ruby file split.
String objects in ruby have a method called split it is similar to the split function of perl it can cut up a string into pieces along a pre defined string or regex returning an array of smaller strings.
On unix based systems permissions are.
All the i o methods are derived from the class io.
In the description of file methods permission bits are a platform specific set of bits that indicate permissions of a file.
Ruby s split and strip methods are helpful tools in being able to work with the string data type especially when you need to have the ability to iterate over the string values.
It will remove nothing at all from the original string and split on every character.
Note different os use different line format unix uses n windows r n macos uses n.
This essentially turns the string into an array of equal length containing only one character strings one for each character in the string.
This chapter will cover all the basic i o functions available in ruby.
If split s first argument is a string the characters in that string are used as a string separator delimiter whereas in comma delimited data the comma is used to separate data.
Using file read and then split into lines another method is to read the content into one buffer and then split it into lines.
A file is an abstraction of any file object accessible by the program and is closely associated with class io file includes the methods of module filetest as class methods allowing you to write for example file exist foo.
The class io provides all the basic methods such as read write gets puts readline getc and printf.
If number 200 puts number end end output 200 300.
Ruby program that uses split parses integers line 100 200 300 split on the comma char.
Ruby provides a whole set of i o related methods implemented in the kernel module.
