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 com-
		      mand 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.

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
