Synopsis

[address1[,address2]]D

Delete the first part (up to embedded newline) of a multiline pattern space created by the N command, and resume editing with the first command in the script. If this command empties the pattern space, then a new line of input is read, as if the d command had been executed.

Example

# Strip multiple blank lines, leaving only one:
/^$/{
N
/^\n$/D
}
