1 15 GRUB environment variables
1 *****************************
1 
1 GRUB supports environment variables which are rather like those offered
1 by all Unix-like systems.  Environment variables have a name, which is
1 unique and is usually a short identifier, and a value, which is an
1 arbitrary string of characters.  They may be set (⇒set), unset
1 (⇒unset), or looked up (⇒Shell-like scripting) by name.

1    A number of environment variables have special meanings to various
1 parts of GRUB. Others may be used freely in GRUB configuration files.
