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.


OPERANDS
     The following operand is supported:

     process-id    process ID

User Commands                                            gcore(1)



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
