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:
-ccontent
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.
-ofilename
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.
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 process 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
