N

[address1 [, address2 ]]N

Append next input line to contents of pattern space; the new line is separated from the previous contents of the pattern space by a newline. (This command is designed to allow pattern matches across two lines.) Using \n to match the embedded newline, you can match patterns across multiple lines. See Example under D .

Examples

Like the Example in n , but print .NH line as well as header title:

/^\.NH/{
N
p
}

Join two lines (replace newline with space):

/^\.NH/{
N
s/\n/ /
p
}
