LogsGrep is a unique, grep-like utility designed specifically to target log files containing multi-line entries.
The primary target is Java log files (Log4J, common, ...), where it is very common to have multiline log entries (for example log entries with a stacktrace).
It follows Unix philosophy, does only its primary job and expects its input to be generated by other more advanced tools (tail, cat, type, find...);
There is no goal to be compatible with Unix grep.
LogsGrep is written in the Java programming langue having performance and low resource usage in mind (no strings, no object creation, stream-processing).
You can find all neccessary information from README file.
