Cross-device link error

Working through Pine’s Programming book and got this error (complete at
bottom):

Cross-device link -…(Errno::EXDEV)

Trying to read photos from a memory card to hard drive and rename them.
Someone posted the same error on the book’s errata page and I didn’t
see a response so though I better look elsewhere

gscar-computer:~ gscar$ ruby “/Users/gscar/Documents/Ruby/Pine-Learning
to Script/RenamingYourPhotos\302\24711.5.y.rb”
What would you like to call this batch?
Testing

Downloading 3 files:
/Users/gscar/Documents/Ruby/Pine-Learning to
Script/RenamingYourPhotos§11.5.y.rb:38:in rename': Cross-device link - /Volumes/CANON_DC/DCIM/100CANON/IMG_2324.JPG or Testing01.jpg (Errno::EXDEV) from /Users/gscar/Documents/Ruby/Pine-Learning to Script/RenamingYourPhotos§11.5.y.rb:38 from /Users/gscar/Documents/Ruby/Pine-Learning to Script/RenamingYourPhotos§11.5.y.rb:28:ineach’
from /Users/gscar/Documents/Ruby/Pine-Learning to
Script/RenamingYourPhotos§11.5.y.rb:28

Line 28 is: picNames.each do |name| 
Line 38 is: File.rename name,
newName

Thanks for any help

You’ve gotta give us some more information. It would be better to
include the whole method than just one line.

File.rename doesn’t copy file content, just change the name.
So it can’t move a file across devices. You may want to use
FileUtils.cp method.
