  • OpenTemporary[ ] opens a temporary file to which output can be written, and returns an OutputStream object.
  • OpenTemporary is often used in conjunction with Put and Get as a way of preparing data that is exchanged between Mathematica and external programs.
  • OpenTemporary always creates a new file, that does not already exist.
  • On Unix systems, OpenTemporary typically creates a file in the /tmp directory.
  • The global variable $TemporaryPrefix gives the base of the file name used by OpenTemporary.
  • See the Mathematica book: Section 2.11.2.
