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.

 

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 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

Since glibc 2.19, pldd is broken: it just hangs when executed. It is unclear if it will ever be fixed.  

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
