tee(1) BSD General Commands Manual tee(1)
tee -- pipe fitting
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 function is expected to be POSIX IEEE Std 1003.2 (``POSIX.2'') compatible. BSD June 6, 1993 BSD
