создать основной файл работающей программы (Generate a core file of a running program)
Имя (Name)
gcore - Generate a core file of a running program
Синопсис (Synopsis)
gcore [-a] [-o prefix] pid1 [pid2...pidN]
Описание (Description)
Generate core dumps of one or more running programs with process
IDs pid1, pid2, etc. A core file produced by gcore is equivalent
to one produced by the kernel when the process crashes (and when
"ulimit -c" was used to set up an appropriate core dump limit).
However, unlike after a crash, after gcore finishes its job the
program remains running without any change.
Параметры (Options)
-a Dump all memory mappings. The actual effect of this option
depends on the Operating System. On GNU/Linux, it will
disable "use-coredump-filter" and enable
"dump-excluded-mappings".
-o prefix
The optional argument prefix specifies the prefix to be used
when composing the file names of the core dumps. The file
name is composed as prefix.pid, where pid is the process ID
of the running program being analyzed by gcore. If not
specified, prefix defaults to gcore.
