systemd Developer Zbigniew Jędrzejewski-Szmek zbyszek@in.waw.pl coredumpctl 1 coredumpctl Retrieve coredumps from the journal coredumpctl OPTIONS COMMAND PID|COMM|EXE|MATCH coredumpctl may be used to retrieve coredumps from systemd-journald8. The following options are understood: --no-legend Do not print the column headers. -1 Show information of a single coredump only, instead of listing all known coredumps. -F --field= Print all possible data values the specified field takes in matching coredump entries of the journal. -o --output=FILE Write the core to FILE. The following commands are understood: list List coredumps captured in the journal matching specified characteristics. If no command is specified, this is the implied default. info Show detailed information about coredumps captured in the journal. dump Extract the last coredump matching specified characteristics. The coredump will be written on standard output, unless an output file is specified with -o/--output. gdb Invoke the GNU debugger on the last coredump matching specified characteristics. A match can be: PID Process ID of the process that dumped core. An integer. COMM Name of the executable (matches COREDUMP_COMM=). Must not contain slashes. EXE Path to the executable (matches COREDUMP_EXE=). Must contain at least one slash. MATCH General journalctl predicates (see journalctl1). Must contain an equal sign. On success, 0 is returned; otherwise, a non-zero failure code is returned. Not finding any matching coredumps is treated as failure. systemd-coredump8, coredump.conf5, systemd-journald.service8, gdb1
