The key word is "occasionally".  You can open the file for append, write your
occasional text to it, and close it again.  In between, the file is available
to other users.

This technique is not recommended if "occasionally" is "frequently".  The
overhead due to opening and closing the file will exceed the time taken to
actually write data into the file, with the result that your program (and the
system) will run quite a bit more slowly.
