PEEKFD(1)                        User Commands                       PEEKFD(1)
NAME
       peekfd - peek at file descriptors of running processes
SYNOPSIS
       peekfd     [-8,--eight-bit-clean]    [-n,--no-headers]    [-f,--follow]
       [-d,--duplicates-removed] [-V,--version] [-h,--help] pid [fd] [fd] ...
DESCRIPTION
       peekfd attaches to a running  process  and  intercepts  all  reads  and
       writes  to file descriptors.  You can specify the desired file descrip-
       tor numbers or dump all of them.
OPTIONS
       -8     Do no post-processing on the bytes being read or written.
       -n     Do not display  headers  indicating  the  source  of  the  bytes
              dumped.
       -c     Also  dump  the  requested  file  descriptor activity in any new
              child processes that are created.
       -d     Remove duplicate read/writes from the output.  If you're looking
              at a tty with echo, you might want this.
       -v     Display a version string.
       -h     Display a help message.
FILES
       /proc/*/fd
              Not  used  but  useful  for the user to look at to get good file
              descriptor numbers.
ENVIRONMENT
       None.
DIAGNOSTICS
       The following diagnostics may be issued on stderr:
       Error attaching to pid ...
              An unknown  error  occurred  while  attempted  to  attach  to  a
              process..  you may need to be root.
BUGS
       Probably  lots.   Don't  be surprised if the process you are monitoring
       dies.
