8 If a backslash ("\") appears within a word then backslash substitution occurs. In all
cases but those described below the backslash is dropped and the following character
is treated as an ordinary character and included in the word. This allows characters
such as double quotes, close brackets, and dollar signs to be included in words without
triggering special processing. The following table lists the backslash sequences that are
handled specially, along with the value that replaces each sequence.
\a
Audible alert (bell) (0x7).
\b
Backspace (0x8).
\f
Form feed (0xc).
\n
Newline (0xa).
\r
Carriage-return (0xd).
\t
Tab (0x9).
\v
Vertical tab (0xb).
\<newline>whiteSpace
A single space character replaces the backslash, newline, and all spaces and tabs
after the newline. This backslash sequence is unique in that it is replaced in a
separate pre-pass before the command is actually parsed. This means that it will
be replaced even when it occurs between braces, and the resulting space will be
treated as a word separator if it isn’t in braces or quotes.
\\
Backslash ("\").
\ooo
The digits ooo (one, two, or three of them) give the octal value of the character.
\xhh
The hexadecimal digits hh give the hexadecimal value of the character. Any
number of digits may be present.
Backslash substitution is not performed on words enclosed in braces, except for
backslash-newline as described above.
