Re^5: dos2ux shows cannot open file if it is greater than 2GB size

[Tux]

That will change *ALL* \r in text, not just trailing \r. I do not think that is what dos2ux is supposed to do, though I admit that HP's manual page isn't very clear on that:

 DESCRIPTION
      dos2ux and ux2dos read each specified file in sequence and write
+ it to
      standard output, converting to HP-UX format or to DOS format,
      respectively.  Each file can be either DOS format or HP-UX forma
+t for
      either command.

      A DOS file name is recognized by the presence of an embedded col
+on (:)
      delimiter; see dosif(4) for DOS file naming conventions.

      If no input file is given or if the argument - is encountered, d
+os2ux
      and ux2dos read from standard input.  Standard input can be comb
+ined
      with other files.
