GCORE(1)GCORE(1)NAME
gcore - get core images of running processes
SYNOPSIS
gcore [-pgF] [-o filename] [-c content] process-id...
DESCRIPTION
The gcore utility creates a core image of each specified process. By
default, the name of the core image file for the process whose process
ID is process-id is core.process-id.
OPTIONS
The following options are supported:
-c content
Produces core image files with the specified content.
The content description uses the same tokens as in core‐
adm(1M). The -c option does not apply to cores produced
due to the -p or -g flags.
-F
Force. Grabs the target process even if another process
has control.
-g
Produces core image files in the global core file repos‐
itory with the global content as configured by core‐
adm(1M). The command fails if the user does not have
permissions to the global core file repository.
-o filename
Substitutes filename in place of core as the first part
of the name of the core image files. filename can con‐
tain the same tokens to be expanded as the paths in
coreadm(1M).
-p
Produces a core image file in the process-specific loca‐
tion with the process-specific content for each process
as configured by coreadm(1M). The command fails if the
user does not have permissions to the per-process core
file repository.
OPERANDS
The following operand is supported:
process-id
process ID
USAGE
Caution should be exercised when using the -F flag. Imposing two con‐
trolling processes on one victim process can lead to chaos. Safety is
assured only if the primary controlling process, typically a debugger,
has stopped the victim process and the primary controlling process is
doing nothing at the moment of application of the proc tool in ques‐
tion.
EXIT STATUS
The following exit values are returned:
0
On success.
non-zero
On failure, such as non-existent process ID.
FILES
core.process-id
core images
