@chapter Invoking grub-mkrelpath
The program @command{grub-mkrelpath} makes a file system path relative to
the root of its containing file system. For instance, if @file{/usr} is a
mount point, then:
@example
$ @kbd{grub-mkrelpath /usr/share/grub/unicode.pf2}
@samp{/share/grub/unicode.pf2}
@end example
This is mainly used internally by other GRUB utilities such as
@command{grub-mkconfig} (@pxref{Invoking grub-mkconfig}), but may
occasionally also be useful for debugging.
@command{grub-mkrelpath} accepts the following options:
@table @option
@item --help
Print a summary of the command-line options and exit.
@item --version
Print the version number of GRUB and exit.

@chapter Invoking grub-script-check
The program @command{grub-script-check} takes a GRUB script file
(@pxref{Shell-like scripting}) and checks it for syntax errors, similar to
commands such as @command{sh -n}. It may take a @var{path} as a non-option
argument; if none is supplied, it will read from standard input.
@example
grub-script-check /boot/grub/grub.cfg
@end example
@command{grub-script-check} accepts the following options:
@table @option
@item --help
Print a summary of the command-line options and exit.
@item --version
Print the version number of GRUB and exit.
@item -v
@itemx --verbose
Print each line of input after reading it.
