NAME         top

       pldd - display dynamic shared objects linked into a process

SYNOPSIS         top

       pldd pid
       pldd option

DESCRIPTION         top

       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         top

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

              Display a short usage message and exit.

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

EXIT STATUS         top

       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         top

       pldd is available since glibc 2.15.

CONFORMING TO         top

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

NOTES         top

       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         top

       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         top

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