January 9, 2005 GCORE 1

### NAME

gcore - get core images of running process

### SYNOPSIS

gcore [-c corename] pid [pid ...]

### DESCRIPTION

gcore creates a core image of the specified processes suitable for use with gdb(1). By default, the core is written to the file `````<progname>.core`'', where ``<```progname`>'' is the program name of the process corresponding to the pid that is given on the command line. This filename can be changed by supplying the -c corename argument, or setting `````proc.<pid>.corename`'' with sysctl(8).

### FILES

```<progname>.core`
  The core image.

### SEE ALSO

gdb(1), sysctl(8)

### HISTORY

gcore appeared in BSD 4.2, disappeared in NetBSD1.2, and reappeared in NetBSD2.0.

### BUGS

The process is not stopped while the core file is generated, so it might not be consistent.
