Dir.entries showing . and .. , how come?

[Mmcolli00 Mom]

Why is it that there are '.' and '..' in my output? I want to create a
list of all the files in this directory without showing the . and .. at
the top of the list. What do you do for this? Thanks, M

#snippet
myfolder = "c:/myfolder"

Dir.entries(myfolder).each do |filename|
puts filename
end
#end snippet

#Shows this as output

Those are hidden directories on Unix, pointing to the current and parent
directory. I'm not sure why they're on Windows, too...

I'd do this:

#snippet
myfolder = "c:/myfolder"

Dir.entries(myfolder).each do |filename|
puts filename unless filename =~ /^\.\.?$/
end
#end snippet

You could do it other ways, too. I'm not sure which is faster.

Of course, this might still not do what you want -- it's going to include
folders, too. If you just want files, you could do something like this:

Dir.entries(myfolder).each do |filename|
puts filename if File.file?(filename)
end

Thanks David, I try them out now! -Misty

I'd do this:I

#snippet
myfolder =3D "c:/myfolder"

Dir.entries(myfolder).each do |filename|
=A0puts filename unless filename =3D~ /^\.\.?$/
end
#end snippet

end

I would just do something like this:

Dir.entries(dir).reject{|entry| entry =3D~ /^\.{1,2}$/}

But my regex-fu may be weak. Since it's only 2 possibilities, it might
be simpler to just do this:

Dir.entries(dir).reject{|entry| entry =3D=3D "." || entry =3D=3D ".."}


That's really just semantics, though.

On unix, Dir.glob doesn't return hidden files(like Dir.entries does):


dirname = "whatever"

Dir.glob("#{dirname}/*").each do |fname|
puts fname
end

On unix, Dir.glob doesn't return hidden files(like Dir.entries does):
dirname =3D "whatever"

Dir.glob("#{dirname}/*").each do |fname|
puts fname
end
--=20

Unless you want it to:
Dir.glob("*") #=3D> ["config.h", "main.rb"]
Dir.glob("*", File::FNM_DOTMATCH) #=3D> [".", "..", "config.h", =20
"main.rb"]

dirname = "whatever"

Dir.glob("#{dirname}/*").each do |fname|
puts fname
end

this returned 1 nil since first file in the directory was not the file
for the condition. (ex. "AUR")
