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.

Ruby file split. This essentially turns the string into an array of equal length containing only one character strings one for each character in the string. Values each do v number integer v display number if it is greater than or equal to 200. Ruby program that uses split parses integers line 100 200 300 split on the comma char. The class io provides all the basic methods such as read write gets puts readline getc and printf.

Using file read and then split into lines another method is to read the content into one buffer and then split it into lines. Values line split parse each number in the result array. If number 200 puts number end end output 200 300. It will remove nothing at all from the original string and split on every character.

On unix based systems permissions are. Ruby provides a whole set of i o related methods implemented in the kernel module. 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. This chapter will cover all the basic i o functions available in ruby.

If the delimiter passed to string split is a zero length string or regular expression then string split will act a bit differently. 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. All the i o methods are derived from the class io. Note different os use different line format unix uses n windows r n macos uses n.
