pldd(1) General Commands Manual pldd(1)
NAME
pldd - display dynamic shared objects linked into a process
SYNOPSIS
pldd pid
pldd option
DESCRIPTION
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).
OPTIONS
--help
-? Display a help message and exit.
--usage
Display a short usage message and exit.
--version
-V Display program version information and exit.
EXIT STATUS
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 ex-
ists with a status of 1. If given an invalid option, it exits with the
status 64.
VERSIONS
Some other systems have a similar command.
STANDARDS
None.
HISTORY
glibc 2.15.
NOTES
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 speci-
fied pid):
$ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" \
-ex "quit" -p $pid | grep '^0x.*0x'
BUGS
From glibc 2.19 to glibc 2.29, pldd was broken: it just hung when exe-
cuted. This problem was fixed in glibc 2.30, and the fix has been
backported to earlier glibc versions in some distributions.
