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       Some other systems have a similar command.

STANDARDS

HISTORY

42       glibc 2.15.
43

NOTES

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

BUGS

61       From glibc 2.19 to glibc 2.29, pldd was broken: it just hung when  exe‐
62       cuted.   This  problem  was  fixed  in glibc 2.30, and the fix has been
63       backported to earlier glibc versions in some distributions.

67       1143
68       $ pldd $$               # Display DSOs linked into the shell
