[address]a\

text

[address1[,address2]]a \ {G}

text

Append text following each line matched by address.Iftext goes

over more than one line, newlines must be “hidden” by preceding

them with a backslash. The text is terminated by the first newline

that is not hidden in this way. The text is not available in the

pattern space, and subsequent commands cannot be applied to it.

The results of this command are sent to standard output when the

list of editing commands is finished, regardless of what happens to

the current line in the pattern space.

The GNU version accepts two addresses and allows you to put the

first line of text on the same line as the a command.

Example

$a\

This goes after the last line in the file\

(marked by $). This text is escaped at the\

end of each line, except for the last one.

b

[address1[,address2]]b[label]

Unconditionally transfer control to :label elsewhere in script. That

is, the command following the label is the next command applied

to the current line. If no label is specified, control falls through to

the end of the script, so no more commands are applied to the

current line.

Example

# Ignore HTML tables; resume script after </table>:

/<table/,/<\/table>/b

c

[address1[,address2]]c\

text

Replace (change) the lines selected by the address(es) with text.
