WebWhen you use expr >>> file, Mathematica appends each new expression you give to the end of your file. If you use expr >> file, however, then Mathematica instead wipes out anything that was in the file before, and then puts expr into the file. This writes an expression to the file tmp. In[4]:= Factor@x^6 - 1D >> tmp Here are the contents of the file.
