* docs/grub.texi (Simple configuration): Document GRUB_CMDLINE_XEN

GRUB_GFXPAYLOAD_LINUX=text rather than unsetting it in order to
disable gfxpayload.
(Shell-like scripting): Add real content.
(Serial terminal): Suggest `terminal_input serial; terminal_output
serial' rather than putting the two commands on separate lines,
since console input will be inoperative after the first command.

Vladimir Serbinenko).

@node Shell-like scripting
@section Writing full configuration files directly
@c Some of this section is derived from the GNU Bash manual page, also
@c copyrighted by the FSF.
@file{grub.cfg} is written in GRUB's built-in scripting language, which has
a syntax quite similar to that of GNU Bash and other Bourne shell
derivatives.
@heading Words
A @dfn{word} is a sequence of characters considered as a single unit by
GRUB. Words are separated by @dfn{metacharacters}, which are the following
plus space, tab, and newline:
@example
@{ @} | & $ ; < >
@end example
Quoting may be used to include metacharacters in words; see below.
@heading Reserved words
Reserved words have a special meaning to GRUB. The following words are
recognised as reserved when unquoted and either the first word of a simple
command or the third word of a @code{for} command:
@example
! [[ ]] @{ @}
case do done elif else esac fi for function
if in menuentry select then time until while
@end example
Not all of these reserved words have a useful purpose yet; some are reserved
for future expansion.
@heading Quoting
Quoting is used to remove the special meaning of certain characters or
words. It can be used to treat metacharacters as part of a word, to prevent
reserved words from being recognised as such, and to prevent variable
expansion.
There are three quoting mechanisms: the escape character, single quotes, and
double quotes.
A non-quoted backslash (\) is the @dfn{escape character}. It preserves the
literal value of the next character that follows, with the exception of
newline.
Enclosing characters in single quotes preserves the literal value of each
character within the quotes. A single quote may not occur between single
quotes, even when preceded by a backslash.
Enclosing characters in double quotes preserves the literal value of all
characters within the quotes, with the exception of @samp{$} and @samp{\}.
The @samp{$} character retains its special meaning within double quotes.
The backslash retains its special meaning only when followed by one of the
following characters: @samp{$}, @samp{"}, @samp{\}, or newline. A
backslash-newline pair is treated as a line continuation (that is, it is
removed from the input stream and effectively ignored). A double quote may
be quoted within double quotes by preceding it with a backslash.
@heading Variable expansion
The @samp{$} character introduces variable expansion. The variable name to
be expanded may be enclosed in braces, which are optional but serve to
protect the variable to be expanded from characters immediately following it
which could be interpreted as part of the name.
Normal variable names begin with an alphabetic character, followed by zero
or more alphanumeric characters.
Positional variable names consist of one or more digits. These are reserved
for future expansion.
The special variable name @samp{?} expands to the exit status of the most
recently executed command.
@heading Comments
A word beginning with @samp{#} causes that word and all remaining characters
on that line to be ignored.
@heading Simple commands
A @dfn{simple command} is a sequence of words separated by spaces or tabs
and terminated by a semicolon or a newline. The first word specifies the
command to be executed. The remaining words are passed as arguments to the
invoked command.
The return value of a simple command is its exit status.
@heading Compound commands
A @dfn{compound command} is one of the following:
@table @asis
@item for @var{name} in @var{word} @dots{}; do @var{list}; done
The list of words following @code{in} is expanded, generating a list of
items. The variable @var{name} is set to each element of this list in turn,
and @var{list} is executed each time. The return value is the exit status
of the last command that executes. If the expansion of the items following
@code{in} results in an empty list, no commands are executed, and the return
status is 0.
@item if @var{list}; then @var{list}; [elif @var{list}; then @var{list};] @dots{} [else @var{list};] fi
The @code{if} @var{list} is executed. If its exit status is zero, the
@code{then} @var{list} is executed. Otherwise, each @code{elif} @var{list}
is executed in turn, and if its exit status is zero, the corresponding
@code{then} @var{list} is executed and the command completes. Otherwise,
the @code{else} @var{list} is executed, if present. The exit status is the
exit status of the last command executed, or zero if no condition tested
true.
@item while @var{cond}; do @var{list}; done
@itemx until @var{cond}; do @var{list}; done
The @code{while} command continuously executes the @code{do} @var{list} as
long as the last command in @var{cond} returns an exit status of zero. The
@code{until} command is identical to the @code{while} command, except that
the test is negated; the @code{do} @var{list} is executed as long as the
last command in @var{cond} returns a non-zero exit status. The exit status
of the @code{while} and @code{until} commands is the exit status of the last
@code{do} @var{list} command executed, or zero if none was executed.
@item function @var{name} @{ @var{command}; @dots{} @}
This defines a function named @var{name}. The @dfn{body} of the function is
the list of commands within braces, each of which must be terminated with a
semicolon or a newline. This list of commands will be executed whenever
@var{name} is specified as the name of a simple command. Function
definitions do not affect the exit status in @code{$?}. When executed, the
exit status of a function is the exit status of the last command executed in
the body.
@item menuentry @var{title} [@option{--class=class} @dots{}] [@option{--users=users}] [@option{--hotkey=key}] @{ @var{command}; @dots{} @}
@xref{menuentry}.
