tee

 
Read from standard input and write to standard output and files (or commands). More information: https://www.gnu.org/software/coreutils/tee.
 
  • Copy standard input to each file, and also to standard output:
     
    echo "example" | tee {{path/to/file}}
     
  • Append to the given files, do not overwrite:
     
    echo "example" | tee -a {{path/to/file}}
     
  • Print standard input 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)
