Hi,all:
I have the text like this:
xxxx
xxxx
xxx sum = 1,
xx
xx
xx
d_bits
xxx
xxx
xx sum =0
xx
xx
xx
d_bit
xx
My question is : How can I read the nextline after the d_bits if sum = 1?
$ echo "xxxx
xxxx
xxx sum = 1,
xx
xx
xx
d_bits
x1xx
x2xx
xx sum =0
xx
xx
xx
d_bit

" | perl -ne'/sum\s*=\s*(\d+)/ and $sum = $1; print scalar <> if
/d_bits/ && $sum == 1'
x1xx
