gcore(1)                                                           gcore(1)

NAME
     gcore - get core images of running processes

SYNOPSIS
     gcore [-o filename] processid ...

DESCRIPTION
     gcore creates a core image of each specified process. Such an image
     may be used with debuggers such as fsdb.

OPTIONS
     -o not specified:
          gcore creates a core image for each process whose process ID is
          specified in the argument list. The core image is stored in the
          file core.processid.

     -o filename
          (output file) The core image is stored in the file
          filename.processid instead of core.processid.

     processid
          Process ID of the process for which a core image is to be
          created. More than one process ID may be specified.

EXAMPLES
     First, print an overview of all running processes with the ps command:

     $ ps
        PID TTY     TIME COMD
      27623 tty004  0:02 sh
      27691 tty004  0:00 ps

     The process ID of each process is shown in the first column. The gcore
     command can now be called to store a core image of the sh process in a
     file:

     $ gcore 27623
     gcore: core.27623 dumped

     $ ls -l
     total 64
     -rw-r--r--   1 cmd      cmdog      30016 Mar 19 13:08 core.27623
     -rw-------   1 cmd      cmdag        690 Mar 18 14:00 file
     -rw-r--r--   1 cmd      cmdag         63 Mar 13 09:29 startup

     As you can see, the core image is saved in the file core.27623 and can
     be processed further as required.

FILES
     ./core.processid
          File containing the core image for the process identified by
          processid.
