GCORE(1)

NAME
gcore - Generate a core file of a running program

SYNOPSIS
gcore [-a] [-o prefix] [-d directory] pid1 [pid2...pidN]

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.

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.

-d directory
    Use directory as the data directory when invoking ROCgdb for running the gcore command. This argument is optional.
