address@hidden Command date [[year-]month-day] [hour:minute[:second]]
+With no arguments, print the current date and time.
+
+Otherwise, take the current date and time, change any elements specified as
+arguments, and set the result as the new date and time.  For example, `date
+01-01' will set the current month and day to January 1, but leave the year,
+hour, minute, and second unchanged.

address@hidden Command echo address@hidden address@hidden string @dots{}
+Display the requested text and, unless the @option{-n} option is used, a
+trailing new line.  If there is more than one string, they are separated by
+spaces in the output.  As usual in GRUB commands, variables may be
+substituted using @address@hidden@}}.
+
+The @option{-e} option enables interpretation of backslash escapes.  The
+following sequences are recognised:
+
address@hidden @code
address@hidden \\
+backslash
+
address@hidden \a
+alert (BEL)
+
address@hidden \c
+suppress trailing new line
+
address@hidden \f

+new line
+

+carriage return
+
address@hidden \t
+horizontal tab
+
address@hidden \v
+vertical tab
address@hidden table
+
+When interpreting backslash escapes, backslash followed by any other
+character will print that character.
