<tool, operating system> A Unix command which copies its
standard input to its standard output (like cat) but
also to a file given as its argument. tee is thus useful in
pipelines of Unix commands (see plumbing) where it
allows you to create a duplicate copy of the data stream.
E.g.
egrep Unix Dictionary | tee /dev/tty | wc -l
searches for lines containing the string "Unix" in the file
"Dictionary", prints them to the terminal (/dev/tty) and
counts them.
Unix manual page: tee(1).
