NAME
       coredumpctl - Retrieve coredumps from the journal
SYNOPSIS
       coredumpctl [OPTIONS...] {COMMAND} [PID|COMM|EXE|MATCH...]
DESCRIPTION
       coredumpctl may be used to retrieve coredumps from systemd-journald(8).
OPTIONS
       The following options are understood:
       --no-legend
           Do not print 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.
       -h, --help
           Print a short help text and exit.
       --version
           Print a short version string and exit.
       --no-pager
           Do not pipe output into a pager.
       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.
MATCHING
       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 journalctl(1)). Must contain an
           equal sign.
EXIT STATUS
       On success, 0 is returned; otherwise, a non-zero failure code is
       returned. Not finding any matching coredumps is treated as failure.
EXAMPLES
       Example 1. List all the coredumps of a program named foo
           # coredumpctl list foo
       Example 2. Invoke gdb on the last coredump
           # coredumpctl gdb
       Example 3. Show information about a process that dumped core, matching
       by its PID 6654
           # coredumpctl info 6654
       Example 4. Extract the last coredump of /usr/bin/bar to a file named
       bar.coredump
           # coredumpctl -o bar.coredump dump /usr/bin/bar
