Warning:

string1 << string2

modifies string1 by adding the contents of string2. So here you are
modifying SRCDIR, which is probably not what you want, especially if you're
going round this in a loop.

SRCDIR='/tmp'
puts SRCDIR<<'/bar' # '/tmp/bar'
puts SRCDIR # '/tmp/bar'

Use + to concatenate two strings and get the result as a third,
newly-created string.

How to get the Dirname Dir.entries(SRCDIR).sort[2] into the string
for method File.open ?

File.open(SRCDIR + '/' + Dir.entries(SRCDIR).sort[2] + '/foobar.TXT')

or

File.open("#{SRCDIR}/#{Dir.entries(SRCDIR).sort[2]}/foobar.TXT")
