pldd(1)


NAME

   pldd - display dynamic shared objects linked into a process

SYNOPSIS

   pldd pid
   pldd option

DESCRIPTION

   The pldd command displays a list of the dynamic shared objects that are
   linked into the process  with  the  specified  process  ID.   The  list
   includes   the  libraries  that  have  been  dynamically  loaded  using
   dlopen(3).

OPTIONS

   -?, --help
          Display program help message.

   --usage
          Display a short usage message.

   -V, --version
          Display the program version.

EXIT STATUS

   On success, pldd exits with the status 0.   If  the  specified  process
   does not exist, the user does not have permission to access its dynamic
   shared object list, or no command-line  arguments  are  supplied,  pldd
   exists  with  a status of 1.  If given an invalid option, it exits with
   the status 64.

VERSIONS

   pldd is available since glibc 2.15.

CONFORMING TO

   The pldd command is not specified by POSIX.1.  Some other systems  have
   a similar command.

NOTES

   The command

        lsof -p PID

   also  shows  output  that  includes the dynamic shared objects that are
   linked into a process.

   The gdb(1) info shared command also shows the  shared  libraries  being
   used  by a process, so that one can obtain similar output to pldd using
   a command such as the  following  (to  monitor  the  process  with  the
   specified pid):

       $ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" \
               -ex "quit" -p $pid | grep '^0x.*0x'

BUGS

   Since  glibc  2.19, pldd is broken: it just hangs when executed.  It is
   unclear if it will ever be fixed.

EXAMPLE

   $ echo $$               # Display PID of shell
   1143
   $ pldd $$               # Display DSOs linked into the shell
   1143:     /usr/bin/bash
