## Description

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

## Options

The following options are understood:

`--help`
`-h`

  Print a short help text and exit.

`--version`

  Print a short version string and exit.

`--output=FILE`
`-o FILE`

  Write the core to `FILE`.

`--no-pager`

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

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`.

## 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`

  General journalctl predicates (see journalctl 1). Must contain an equals sign.

## Exit status

On success 0 is returned, a non-zero failure code otherwise. Not finding any mathing coredumps is treated as failure.
