P

[address1][,address2]P

Print first part (up to embedded newline) of multi-line pattern created by N command. Same as p if N has not been applied to a line.

Example

Suppose you have function references in two formats:

function(a,b,c)
function(a,
         b,
         c)

The following script changes argument c, regardless of whether it appears on the same line as the function name:

s/function(a,b,c)/function(a,b,XX)/
/function(/{
N
s/c/XX/
P
D
}
