usage of getline

[epidor]

Is there someone to give the meaning of this :

awk'BEGIN
$1=="coucou" {getline;print;getline {for (i=NF;i>1;i--)getline;print}}'> file2

 

[CaKiwi]

For every line in which the first field is "coucou" do the following:

Read the next line and print it.
Read the next line. read a number of lines equal to the number of fields in this line minus one.
Print the last line read.

yeah, that's sounds right, but.......... there's no 'execution block' definition for the 'BEGIN' clause.

The script as is will produce a syntax error when ran.
