pldd(1) General Commands Manual pldd(1)
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.
--version
-V 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.
Some other systems have a similar command.
None.
glibc 2.15.
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 glibc 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.
