pldd - display dynamic shared objects linked into a process
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)
- -?, --help
- Display program help message.

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
with a status of 1. If given an invalid option, it exits with the status 64.
is available since glibc 2.15.
command is not specified by POSIX.1. Some other systems have a
lsof -p PID
also shows output that includes the dynamic shared objects that are linked into
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
$ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" \
-ex "quit" -p $pid | grep '^0x.*0x'
Since glibc 2.19, pldd
is broken: it just hangs when executed. It is
unclear if it will ever be fixed.
