coredump(1)							   coredump(1)

       coredump - Creates a core snapshot of a running process

       coredump [directory] pid

       A  directory in which to put the core snapshot. The default is the cur‐
       rent directory.	The process id of the running process.

       The coredump command creates a core snapshot of a running  process.  To
       use  the	 coredump  command,  you: Must have root privileges or own the
       process specified (pid).	 Must have procfs enabled.

       By default, the snapshot is placed in a file named core, in the current
       directory. You can specify a different directory with the directory op‐
       erand. If core-file-naming is enabled  at  the  system  or  application
       level  (see  the Programmer's Guide), the core file will be named auto‐
       matically according to the following  convention:

       where tag is a uniquely assigned number.

       To examine the core snapshot, use the dbx(1) debugger or the ladebug(1)
       debugger (if installed) as you  would  when  examining  the  core  dump
       resulting from a program crash.

       If  any	of the following conditions occurs, errno is set to the corre‐
       sponding value: No such process. There is no running process with  that
       process	id.   Permission denied.  You do not own the process or do not
       have the necessary privileges.

       The following exit values  are  returned:  Successful  completion.   An
       error occurred.

       Default	name  of  a core snapshot file.	 Location of the coredump pro‐

       dbx(1), ladebug(1), proc(4).
