tee -- Command

Copy input to multiple output streams
tee [ -a ] [ -i ] [ file ...]

tee reads from  standard input, usually a pipe, and  writes to the standard
output, usually a  pipe.  tee also writes a copy  of the input data to each
file specified.

The -a flag  tells tee to append data to  each file, analogous to the shell
construct ``>>file''.  Otherwise,  it creates each file, analogous to
the construct ``>file''.

The flag -i means ignore interrupts.
