24.8 Invoking grub-script-check

The program grub-script-check takes a GRUB script file (see Shell-like scripting) and checks it for syntax errors, similar to commands such as sh -n. It may take a path as a non-option argument; if none is supplied, it will read from standard input.

grub-script-check /boot/grub/grub.cfg

grub-script-check accepts the following options:


Print a summary of the command-line options and exit.


Print the version number of GRUB and exit.


Print each line of input after reading it.
