6 gcore - get core images of running processes

9 gcore [-pgF] [-o filename] [-c content] process-id...

13 The gcore utility creates a core image of each specified process. By
14 default, the name of the core image file for the process whose process
15 ID is process-id is core.process-id.
16
18 The following options are supported:
19
20 -c content Produces core image files with the specified content.
21 The content description uses the same tokens as in core‐
22 adm(1M). The -c option does not apply to cores produced
23 due to the -p or -g flags.
24
25
26 -F Force. Grabs the target process even if another process
27 has control.
28
29
30 -g Produces core image files in the global core file repos‐
31 itory with the global content as configured by core‐
32 adm(1M). The command fails if the user does not have
33 permissions to the global core file repository.
34
35
36 -o filename Substitutes filename in place of core as the first part
37 of the name of the core image files. filename can con‐
38 tain the same tokens to be expanded as the paths in
39 coreadm(1M).
40
41
42 -p Produces a core image file in the process-specific loca‐
43 tion with the process-specific content for each process
44 as configured by coreadm(1M). The command fails if the
45 user does not have permissions to the per-process core
46 file repository.
47
48
50 The following operand is supported:
51
52 process-id process ID
53
54
56 Caution should be exercised when using the -F flag. Imposing two con‐
57 trolling processes on one victim process can lead to chaos. Safety is
58 assured only if the primary controlling process, typically a debugger,
59 has stopped the victim process and the primary controlling process is
60 doing nothing at the moment of application of the proc tool in ques‐
61 tion.
62
64 The following exit values are returned:
65
66 0 On success.
67
68
69 non-zero On failure, such as non-existent process ID.
