I'm running Ruby on Windows though I don't know if that should make a difference. All I want to do is get the current working directory's absolute path. Is this possible from irb? Apparently from a script it's possible using File.expand_path(__FILE__)
But from irb I tried the following and got a "Permission denied" error:
File.new(Dir.new(".").path).expand
Dir.pwd
seems to do the trick.
http://ruby-doc.org/core/Dir.html#method-c-pwd
File.expand_path File.dirname(__FILE__)
will return the directory relative to the file this command is called from.
But Dir.pwd
returns the working directory (results identical to executing pwd
in your terminal)
As for the path relative to the current executing script, since Ruby 2.0 you can also use
__dir__
So this is basically the same as
File.dirname(__FILE__)
This will give you the working directory of the current file.
File.dirname(__FILE__)
Example:
current_file: "/Users/nemrow/SITM/folder1/folder2/amazon.rb"
result: "/Users/nemrow/SITM/folder1/folder2"
If you want to get the full path of the directory of the current rb file:
File.expand_path('../', __FILE__)
Through this you can get absolute path of any file located in any directory.
File.join(Dir.pwd,'some-dir','some-file-name')
This will return
=> "/User/abc/xyz/some-dir/some-file-name"
