pldd - display dynamic shared objects linked into a process
pldd pid
pldd option
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 dlopen(3).
-?, --help
Display a help message and exit.
--usage
Display a short usage message and exit.
-V, --version
Display program version information and exit.
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 similar command.
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'
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.
