      tee [-ai] [file ...]


      The tee utility copies standard input to standard output, making a copy
      in zero or more files.  The output is unbuffered.
      The following options are available:
      -a      Append the output to the files rather than overwriting them.
      -i      Ignore the SIGINT signal.
      The following operands are available:
      file  A pathname of an output file.
      The tee utility takes the default action for all signals, except in the
      event of the -i option.


      The tee utility exits 0 on success, and >0 if an error occurs.


      The tee utility is expected to be IEEE Std 1003.2 (“POSIX.2”) compatible.


Based on BSD UNIX
FreeBSD is an advanced operating system for x86 compatible (including Pentium and Athlon), amd64 compatible (including Opteron, Athlon64, and EM64T), UltraSPARC, IA-64, PC-98 and ARM architectures. It is derived from BSD, the version of UNIX developed at the University of California, Berkeley. It is developed and maintained by a large team of individuals. Additional platforms are in various stages of development.
