Read from stdin and write to stdout and files (or commands). More information: <https://www.gnu.org/software/coreutils/tee>.

  • Copy `stdin` to each file, and also to `stdout`:
    echo "example" | tee path/to/file
  • Append to the given files, do not overwrite:
    echo "example" | tee -a 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)
