Sed line concatenation problem
I have a somewhat bizarre problem when trying to concatenate lines in a file.
Using
Code:
cat file.txt | sed -e :a -e '/$/N;s/\n/ /;ta'

the output in file.txt should go from
Code:
1
2
3

to
Code:
1 2 3

instead I only get the last line or
Code:
3

.
I find that if I open the file in gedit and hit delete in front of every line the code works. I don't believe there are any spaces in front of the lines and the code should still work even if there were. What is going wrong? How do I go about fixing this?

       files that you list on the command line.

OPTIONS

       The following options are supported:

       --debug [-section]      Run gedit in debug mode. In debug mode all  the functions that are being called dump the function names to the con-
			       sole. You can specify the following sections for debugging:

				 o  window

				 o  commands

				 o  document

				 o  file

				 o  plugins

				 o  prefs

				 o  print

				 o  search

				 o  undo

				 o  view

				 o  recent

			       Run gedit --help for more information.
