The following options are understood: -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. --no-legend Do not print the column headers. The following commands are understood: list List coredumps captured in the journal matching specified characteristics. 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. 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 equals sign. On success, 0 is returned; otherwise, a non-zero failure code is returned. Not finding any matching coredumps is treated as failure. systemd-journald.service8, gdb1
