Dir.foreach("c:/wes/photos/Bike/*.JPG") {|x| puts "Got#{x}" }
This does not seem to work on my windows xp machine? Should it? I am
trying to get a list of files with the .JPG extension.
If I take the *.JPG out, I get a list of all of the files in that
directory? What am I doing wrong? I just want the .JPG's.
Thanks in advance,
wes
Dir.foreach("c:/wes/photos/Bike/") { |x| p "got #{x}" if x[x.length-3, x.length]=='JPG' }
I'm sure there's a better way, but this should do the trick

You could do:
Dir["c:/wes/photos/Bike/*.JPG"].each { |x| puts "Got#{x}" }
change JPG to [JPGjpg] to be ignore the case.

You could do:
Dir["c:/wes/photos/Bike/*.JPG"].each { |x| puts "Got#{x}" }change JPG to [JPGjpg] to be ignore the case.
You'd actually need to do:
*.[Jj][Pp][Gg]
With *.[JPGjpg] you'll only match files like file.J and file.p.
You could also do:
*.{jpg,JPG}
if you're sure that those are the only two (i.e., nothing like JpG).

Or
Dir.glob("c:/wes/photos/Bike/*.JPG") { |x| puts "Got#{x}" }

On a Windows box IMHO that should read
Dir.glob("c:\\wes\\photos\\Bike\\*.JPG") { |x| puts "Got#{x}" }
Or - a bit more portable:
Dir[File.join("c:", "wes", "photos", "Bike", "*.jpg")]
Kind regards

Dir.glob("c:\\wes\\photos\\Bike\\*.JPG") { |x| puts "Got#{x}" }
Ruby uses forward-slashes on all platforms.
Or - a bit more portable:
Dir[File.join("c:", "wes", "photos", "Bike", "*.jpg")]
It yields "c:/wes/photos/Bike/*.JPG" even on Windows.
