gcore

gcore(1)                                                           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 will be 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 will fail 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 config-
                       ured by coreadm(1M). The command will fail if the user does not have permissions to the per-process core file repository.

OPERANDS

       The following operand is supported:

       process-id      process ID

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

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
