You did put all the strings into an array called file-link (that is,
unless you are getting a specific error that relates to your strings).
 You could be trying to print or rely upon something that doesn't
exist.  Do you get NilClass errors?

For the unwary, try this to see how multiple assignment works (1.8.6)...

a, b = 1, 2
# a => 1, b => 2
a, b = 1, 2, 3
# a => 1, b => 2 ---- 3 is just lost
a = 1, 2
# a => [1, 2]
a, *b = 1, 2, 3
# a => 1, b => [2, 3]

hth,
