[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.
|
|
|
|
