Such as the above 4 lines.
If not, can anyone suggest a simple script that will do this?
The perl one-liner below demonstrates this. Setting the $/ (input record
separator) var to the empty string causes perl to read in "lines" a

$ cat /tmp/text

$ perl -e'$/=""; while (<>) { print if /green/ }' /tmp/text
