pldd - display dynamic shared objects linked into a process
The pldd 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
Display program help message.
Display a short usage message.
Display the program version.
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.
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 speci-
$ 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.
