NAME

gcore - Generate a core file of a running program

SYNOPSIS

gcore [-o filename] pid

DESCRIPTION

Generate a core dump of a running program with process pid. Produced file is equivalent to a kernel produced core file as if the process crashed (and if "ulimit -c" were used to set up an appropriate core dump limit). Unlike after a crash, after gcore the program remains running without any change.

OPTIONS

-o filename

The optional argument filename specifies the file name where to put the core dump. If not specified, the file name defaults to core.pid, where pid is the running program process

ID.
