systemd-coredumpctl − Retrieve coredumps from the journal


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


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


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.


Do not print the column headers.

−h, −−help

Print a short help text and exit.


Print a short version string and exit.


Do not pipe output into a pager.

The following commands are understood:


List coredumps captured in the journal matching specified characteristics.


Extract the last coredump matching specified characteristics. The coredump will be written on standard output, unless an output file is specified with −o/−−output.


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


Match can be:


Process ID of the process that dumped core. An integer.


Name of the executable (matches COREDUMP_COMM=). Must not contain slashes.


Path to the executable (matches COREDUMP_EXE=). Must contain at least one slash.


General journalctl predicates (see journalctl(1)). 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.
