pldd

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 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.

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.

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.

EXAMPLE

       $ echo $$	       # Display PID of shell
       1143
       $ pldd $$	       # Display DSOs linked into the shell
       1143:	 /usr/bin/bash
       linux-vdso.so.1
       /lib64/libtinfo.so.5
       /lib64/libdl.so.2
       /lib64/libc.so.6
       /lib64/ld-linux-x86-64.so.2
       /lib64/libnss_files.so.2

NOTES

       The command

	    lsof -p PID

       also shows output that includes the dynamic shared objects that are linked into a process.
