See IO.unlink when path is a file.

See Dir.unlink when path is a directory.

Tests if the given command exists in file1, or optionally file2.

Example:

sh[?e, "foo"]
sh[:e, "foo"]
sh["e", "foo"]

Description

public setter for the host component v. (with validation)

see also URI::Generic.check_host

Usage

require 'uri'

uri = URI.parse("http://my.example.com")
uri.host = "foo.com"
# =>  "foo.com"
uri
#=> #<URI::HTTP:0x000000008e89e8 URL:http://foo.com>

extract the host part of the URI and unwrap brackets for IPv6 addresses.

This method is same as URI::Generic#host except brackets for IPv6 (and future IP) addresses are removed.

u = URI("http://[::1]/bar")
p u.hostname      #=> "::1"
p u.host          #=> "[::1]"

set the host part of the URI as the argument with brackets for IPv6 addresses.

This method is same as URI::Generic#host= except the argument can be bare IPv6 address.

u = URI("http://foo/bar")
p u.to_s                  #=> "http://foo/bar"
u.hostname = "::1"
p u.to_s                  #=> "http://[::1]/bar"

If the argument seems IPv6 address, it is wrapped by brackets.
