tee

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

{pipeline}s 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).
