gcore


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



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

     the RLIMIT_CORE value.
