Prints a formatted backtrace to the errors stream if backtraces are enabled.
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"] sh[:exists?, "foo"] sh["exists?", "foo"]
Executes the given command with the options parameter.
Example:
print sh.system("ls", "-l") sh.system("ls", "-l") | sh.head > STDOUT
Executes a block as self
Example:
sh.transact { system("ls", "-l") | head > STDOUT }
v
Public setter for the host component v (with validation).

require 'uri' uri = URI.parse("http://my.example.com") uri.host = "foo.com" uri.to_s #=> "http://foo.com"
Extract the host part of the URI and unwrap brackets for IPv6 addresses.
This method is the same as URI::Generic#host except brackets for IPv6 (and future IP) addresses are removed.
uri = URI("http://[::1]/bar") uri.hostname #=> "::1" uri.host #=> "[::1]"
Sets the host part of the URI as the argument with brackets for IPv6 addresses.
This method is the same as URI::Generic#host= except the argument can be a bare IPv6 address.
uri = URI("http://foo/bar") uri.hostname = "::1" uri.to_s #=> "http://[::1]/bar"
If the argument seems to be an IPv6 address, it is wrapped with brackets.

Patterns to apply to str
Attempts to parse and merge a set of URIs. If no block given, then returns the result, else it calls block for each element in result.
