How to write in an array inside a block?

Ruby
1

Hello,

i want to write all files from my local directory in an array.

Something like (not working):

d = Dir.new("/Volumes/System/")
d.each {|x| file_list.push(x) }

How can i push single filenames through d.each into an array?

Thanks a lot in advance!

If file_list did not exist before the block,
it will not exist after the block exits. Declarations inside blocks
are scoped to the block

I think if you look at the docs for Dir you’ll find a method that will
give you the list of files withtout the need of the block
cheers

Indeed.

irb> file_list = Dir.glob(‘*’)
