.Sh DESCRIPTION
|
|
.Nm
|
|
creates a core image of the specified processes
|

|
where
|
|
.Dq Aq Pa 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
|
|
.Fl c Ar corename
|
|
argument, or setting
|
|
.Dq Pa proc.\*[Lt]pid\*[Gt].corename
|
|
with
|
|
.Xr sysctl 8 .

|
