Unix in a Nutshell, 4th Edition

Name

P

Synopsis

[address1[,address2]]P

Print first part (up to embedded newline) of multiline pattern space 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(arg1, arg2)
function(arg1,
         arg2)

The following script changes argument arg2, regardless of whether it appears on the same line as the function name:

s/function(arg1, arg2)/function(arg1, XX)/
/function(/{
N
s/arg2/XX/
P
D
}
