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 (DSOs)
14       that are linked into the process with the specified process  ID  (PID).
15       The list includes the libraries that have been dynamically loaded using
16       dlopen(3).
17

OPTIONS

19       -?, --help
20              Display a help message and exit.
21
22       --usage
23              Display a short usage message and exit.
24
25       -V, --version
26              Display program version information and exit.
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 ex‐
32       ists with a status of 1.  If given an invalid option, it exits with the
33       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       From  glibc  2.19 to 2.29, pldd was broken: it just hung when executed.
60       This problem was fixed in glibc 2.30, and the fix has  been  backported
61       to earlier glibc versions in some distributions.

EXAMPLES

64       $ echo $$               # Display PID of shell
65       1143
66       $ pldd $$               # Display DSOs linked into the shell
67       1143:   /usr/bin/bash
