How to check if a given directory exists in Ruby
Solution 1:
If it matters whether the file you're looking for is a directory and not just a file, you could use File.directory?
or Dir.exist?
. This will return true only if the file exists and is a directory.
As an aside, a more idiomatic way to write the method would be to take advantage of the fact that Ruby automatically returns the result of the last expression inside the method. Thus, you could write it like this:
def directory_exists?(directory)
File.directory?(directory)
end
Note that using a method is not necessary in the present case.
Solution 2:
You can also use Dir::exist?
like so:
Dir.exist?('Directory Name')
Returns
true
if the 'Directory Name' is a directory,false
otherwise.1
