grub-script-check

The program grub-script-check takes a GRUB script file and checks it for syntax errors. It may take a path as a non-option argument. If none is supplied, it will read from stdin. More information: https://www.gnu.org/software/grub/manual/grub/html_node/Invoking-grub_002dscript_002dcheck.html.

  grub-script-check {{path/to/grub_config_file}}
• Display each line of input after reading it:
  grub-script-check --verbose
• Display version:
  grub-script-check --version
