[section:sed_format Sed Format String Syntax]

Sed-style format strings treat all characters as literals except:

[table

[[character][description]]

[[&][The ampersand character is replaced in the output stream by

the whole of what matched the regular expression. Use

\\& to output a literal '&' character.]]

[[\\][Specifies an escape sequence.]]

]

An escape character followed by any character x, outputs that character unless x

is one of the escape sequences shown below.

[table

[[Escape][Meaning]]

[[\\a][Outputs the bell character: '\\a'.]]

[[\\e][Outputs the ANSI escape character (code point 27).]]

[[\\f][Outputs a form feed character: '\\f']]

[[\\n][Outputs a newline character: '\\n'.]]

[[\\r][Outputs a carriage return character: '\\r'.]]

[[\\t][Outputs a tab character: '\\t'.]]

[[\\v][Outputs a vertical tab character: '\\v'.]]

[[\\xDD][Outputs the character whose hexadecimal code point is 0xDD]]

[[\\x{DDDD}][Outputs the character whose hexadecimal code point is 0xDDDDD]]

[[\\cX][Outputs the ANSI escape sequence "escape-X".]]

[[\\D][If D is a decimal digit in the range 1-9, then outputs the text that matched sub-expression D.]]
