TAP(1)                                                     TAP(1)

     NAME
          tap - follow the pipes of a process

     SYNOPSIS
          tap [ pid ... ]

     DESCRIPTION
          Tap walks the file descriptors of a process looking for
          pipes (see pipe(3)) and then finds the processes on the
          other end of these pipes repeating the process recursively.
          The result is a tree of alternating process and filedescrip-
          tor nodes that make up the process pipeline.
