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 speci‐
       fied 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.

       $ echo $$               # Display PID of shell
       1143
       $ pldd $$               # Display DSOs linked into the shell
