NAME

       systemd-coredumpctl - Retrieve coredumps from the journal

SYNOPSIS

       systemd-coredumpctl [OPTIONS...] {COMMAND} [PID|COMM|EXE|MATCH...]

DESCRIPTION

       systemd-coredumpctl may be used to retrieve coredumps from systemd-journald(8).

OPTIONS

       The following options are understood:

       -h, --help
	   Print a short help text and exit.

       --version
	   Print a short version string and exit.

       -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-pager
	   Do not pipe output of list into a pager.

       --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. Coredump will be written on stdout, unless an output file is specified
	   with -o/--output.

       gdb
	   Invoke the GNU debugger on the last coredump matching specified characteristics.

MATCHING

       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
