Usage: fmtutil [OPTION]... CMD [ARG]...

Rebuild, manage, and otherwise manipulate TeX formats (and Metafont
bases and MetaPost mems).

Valid options:
  --cnffile FILE
  --fmtdir DIRECTORY
  --no-engine-subdir         don't use engine-specific subdir of the fmtdir
  --quiet                    (not implemented, just for compatibility)
  --test                     (not implemented, just for compatibility)
  --dolinks                  (not implemented, just for compatibility)
  --force                    (not implemented, just for compatibility)

Valid commands:
  --all                      recreate all format files
  --missing                  create all missing format files
  --refresh                  recreate only existing format files
  --byengine ENGINENAME      (re)create formats using ENGINENAME
  --byfmt FORMATNAME         (re)create format for FORMATNAME
  --byhyphen HYPHENFILE      (re)create formats that depend on HYPHENFILE
  --enablefmt FORMATNAME     enable formatname in config file
  --disablefmt FORMATNAME    disable formatname in config file
  --listcfg                  list (enabled and disabled) configurations,
                             filtered to available formats
  --catcfg                   output the content of the config file
  --showhyphen FORMATNAME    print name of hyphenfile for format FORMATNAME
  --edit                     edit config file
  --version                  show version info
  --help                     show this message

The config file is named fmtutil.cnf, and
running  kpsewhich fmtutil.cnf  should show the active file.
