NAME

6       pldd - display dynamic shared objects linked into a process
7

SYNOPSIS

9       pldd pid
10       pldd option
11

DESCRIPTION

13       The pldd command displays a list of the dynamic shared objects that are
14       linked into the process  with  the  specified  process  ID.   The  list
15       includes   the  libraries  that  have  been  dynamically  loaded  using
16       dlopen(3).
17

OPTIONS

19       -?, --help
20              Display program help message.
21
22       --usage
23              Display a short usage message.
24
25       -V, --version
26              Display the program version.
27

EXIT STATUS

29       On success, pldd exits with the status 0.   If  the  specified  process
30       does not exist, the user does not have permission to access its dynamic
31       shared object list, or no command-line  arguments  are  supplied,  pldd
32       exists  with  a status of 1.  If given an invalid option, it exits with
33       the status 64.
34

VERSIONS

36       pldd is available since glibc 2.15.
37

CONFORMING TO

39       The pldd command is not specified by POSIX.1.  Some other systems  have
40       a similar command.
41

NOTES

43       The command
44
45           lsof -p PID
46
47       also  shows  output  that  includes the dynamic shared objects that are
48       linked into a process.
49
50       The gdb(1) info shared command also shows the  shared  libraries  being
51       used  by a process, so that one can obtain similar output to pldd using
52       a command such as the following (to monitor the process with the speci‐
53       fied pid):
54
55           $ gdb -ex "set confirm off" -ex "set height 0" -ex "info shared" \
56                   -ex "quit" -p $pid | grep '^0x.*0x'
57

BUGS

59       Since  glibc  2.19, pldd is broken: it just hangs when executed.  It is
60       unclear if it will ever be fixed.

EXAMPLE

63       $ echo $$               # Display PID of shell
64       1143
65       $ pldd $$               # Display DSOs linked into the shell
66       1143:     /usr/bin/bash
