14.3.13 echo

Command: echo [-n] [-e] string …

Display the requested text and, unless the -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 ‘${var}’.

The -e option enables interpretation of backslash escapes. The following sequences are recognised:

\\

backslash

\a

alert (BEL)

\c

suppress trailing new line

\f

form feed

\n

new line

\r

carriage return

\t

horizontal tab

\v

vertical tab

When interpreting backslash escapes, backslash followed by any other character will print that character.
