pldd - display dynamic shared objects linked into a process
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
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.
pldd is available since glibc 2.15.
The pldd command is not specified by POSIX.1. Some other systems have a
- -?, --help
- Display a help message and exit.
- Display a short usage message and exit.
- -V, --version
- Display program version information and exit.
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'
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.
$ echo $$ # Display PID of shell
$ pldd $$ # Display DSOs linked into the shell
