Regex (grep) for multi-line search needed [duplicate]
...character. That is, grep knows where end of line is, but sees the input as one big line.
-o print only matching. Because we're using -z, the whole file is like a single big line, so if there is a match, the entire file would be printed; this way it won't do that.
In regexp:
