pldd - display dynamic shared objects linked into a process
command displays a list of the dynamic shared objects (DSOs) that are

is available since glibc 2.15.
command is not specified by POSIX.1.
Some other systems
have a similar command.
lsof -p PID
also shows output that includes the dynamic shared objects
that are linked into a process.
command also shows the shared libraries being used by a process,
so that one can obtain similar output to
using a command such as the following
(to monitor the process with the specified

-ex "quit" -p $pid | grep '^0x.*0x'
From glibc 2.19 to 2.29,
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.
