ptee reads from one file descriptor (0 / stdin by default) and copies everything to all given output file
       descriptors.  ptee is a piped version of tee(1).

       ptee can be used with pipexec(1) to fit the output of one command into many other commands.

       Duplicate all data from stdin to stdout, stderr and fd 7:
           ptee 1 2 7

       The command
           tee output.txt
       is equivalent to the shell command
           ptee 5 5>output.txt

       Using  pipexec(1):  count  all  files  in  the  file system and additionally count only those that have a
       uppercase 'A' in their name.  The file system  will  be  scanned  only  once.   No  temporary  files  are
       generated.
           pipexec [ LS /bin/ls -R / ] [ PTEE /usr/bin/ptee 3 4 ] \
             [ WC1 /usr/bin/wc -l ] [ GREP /bin/grep A ] \
             [ WC2 /usr/bin/wc -l ] "{LS:1>PTEE:0}" "{PTEE:3>WC1:0}" \
             "{PTEE:4>GREP:0}" "{GREP:1>WC2:0}"

       -rinfd
              use the given infd as input file descriptor.  If this is not specified, 0 (stdin) is used.
