pipetee

A simple, fast, no-dependencies UNIX utility to print the contents of stdin to the terminal and forward them to stdout at the same time.

Example usage:

```sh

output from pt will interleave with output from

sed at the granularity of the buffer

$ yes 'yes' | pt | sed 's/yes/no/g' no no no no no .. no yes yes yes yes yes .. yes no no no no no .. no ^C

$ yes 'yes' | ./target/release/pt -b 3 | sed 's/yes/no/g' yeno s yno es no no yesno no no

yes yno es no no yesno no ^C ```

```sh

look at intermediate results if the final output takes a long time.

$ cat numbers.txt | ./computation-with-incremental-results.py | pt | sort -n | tee output.txt

How does it work?

It reads from stdin and writes to both stdout and /dev/tty. Your shell will redirect stdout to whatever the next pipe is, but /dev/tty (what stdout defaults to on most shells) will remain untouched.
