 To transport data between SDF and your local (or any other external) machine, there are various ways. Their availability depends on your member level on SDF (see the [[http://sdf.org/index.cgi?faq?MEMBERS|FAQ, MEMBER section]] for more information), the external system, and their connection. To transport data between SDF and your local (or any other external) machine, there are various ways.

 For transferring small amount of text data (scripts, tables, source code snippets), think about copy/paste directly in the terminal! If you are [[http://sdf.org/index.cgi?faq?MEMBERS?01|MetaARPA]], then you can use "screen" and its built-in copy facility to transfer data between different screens. For transferring small amount of text data (scripts, tables, source code snippets), think about copy/paste directly in the terminal!

-To append text input in the terminal to a file on SDF, you can open the file on SDF in your favourite [[http://sdf.org/index.cgi?faq?BASICS?09|text editor]]. Or simply use the command "cat >>//file//", send the data to the terminal (via the paste function), and finish with a single line containing only ^D (CTRL-D) - to do that in the terminal, hit RETURN, CTRL-D, RETURN; this will close the standard input the "cat" was reading from.+To append text input in the terminal to a file on SDF, you can open the file on SDF in your favourite [[http://sdf.org/index.cgi?faq?BASICS?09|text editor]].
