Append to the given files, do not overwrite:

echo "example" | tee {{[-a|--append]}} {{path/to/file}}

Print stdin to the terminal, and also pipe it into another program for further processing:

echo "example" | tee {{/dev/tty}} | {{xargs printf "[%s]"}}

Create a directory called "example", count the number of characters in "example" and write "example" to the terminal:

echo "example" | tee >(xargs mkdir) >(wc {{[-c|--bytes]}})
