## 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)](https://www.chedong.com/phpMan.php/man/dlopen/3/markdown).

## 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  argu‐
       ments  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)](https://www.chedong.com/phpMan.php/man/gdb/1/markdown) _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 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 distribu‐
       tions.

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

       /lib64/libtinfo.so.5
       /lib64/libdl.so.2
       /lib64/libc.so.6
       /lib64/ld-linux-x86-64.so.2
