How to get filename without extension from file path in Ruby

Question

How can I get the filename from a file path in Ruby?

For example if I have a path of "C:projectslah.dll" and I just want the "blah".

Is there a LastIndexOf method in Ruby?

Answer 1

Try File.basename

Returns the last component of the filename given in file_name, which must be formed using forward slashes (``/’’) regardless of the separator used on the local file system. If suffix is given and present at the end of file_name, it is removed.

File.basename("/home/gumby/work/ruby.rb")          #=> "ruby.rb"
File.basename("/home/gumby/work/ruby.rb", ".rb")   #=> "ruby"

In your case:

File.basename("C:\projects\blah.dll", ".dll")  #=> "blah"
