Program Description


TEE is an OS/2 mode utility that copies "stdin" to both "stdout"
and "stderr" until an End of File condition is detected. It is
useful in situations where the output of a program (such as MAKE)
needs to be sent to more than one destination (such as the
console and a disk file).

The OS/2 MAKE utility is a good example. With long and complex
make files, invoking MAKE with:

MAKE file

could causes MAKE's output to scroll off the screen, perhaps
allowing an important warning or error message to be overlooked.
Simply redirecting makes output with:

MAKE file 2>&1 >file.err

will save all output but gives no the user no indication MAKE's
progress ("2>&1" ensures all output will be redirected). Piping
MAKE's output through MORE with:

MAKE file 2>&1 | MORE

displays MAKE's progress but requires the user be present to hit
a key after each full screen before MAKE finishes. Piping MAKE's
output through TEE with:

MAKE file 2>&1 | TEE >file.err

yields the benefits of both methods without the drawbacks. MAKE's
output is displayed without pauses while, at the same time, a
copy is redirected to a disk file. The output can then be
reviewed, screen by screen, with:
