User Commands 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 coreadm(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 repository with the global content as
configured by coreadm(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 contain the same tokens
to be expanded as the paths in coreadm(1M).
-p Produces a core image file in the process-
specific location 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.

User Commands gcore(1)
OPERANDS
The following operand is supported:
process-id process ID
USAGE
Caution should be exercised when using the -F flag. Imposing
two controlling 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 pro-
cess and the primary controlling process is doing nothing at
the moment of application of the proc tool in question.
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
