PLDD(1)                                 Linux User Manual                                 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 (DSOs) that are linked into
       the process with the specified process ID (PID).  The list  includes  the  libraries  that
       have been dynamically loaded using dlopen(3).

OPTIONS
       -?, --help
              Display a help message and exit.

       --usage
              Display a short usage message and exit.

       -V, --version
              Display program version information and exit.

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 moni-
       tor 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
       From glibc 2.19 to 2.29, pldd was broken: it just hung when executed.   This  problem  was
       fixed  in  glibc  2.30,  and the fix has been backported to earlier glibc versions in some
       distributions.

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