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.

       --version
       -V     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

       Some other systems have a similar command.

STANDARDS

       None.

HISTORY

       glibc 2.15.

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

       From glibc 2.19 to glibc 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.

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