Open Source Logging Software

Provide a plugabble and configurable alternative to UNIX tools like grep, awk, tail, head, cut, sort, uniq or even some perl based scripts in a Java environment. A bit like what Apache Ant means to good old make.

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).

A command line tool for text file analyis, filtering, splitting and reporting. Runs under Java (1.5+), supports plugins written in Groovy. Has nix and win batch files in distributions.

rtgrep is a bash script which searches for all files in the current directory or a given base directory which were created/modified within a given time period. The search can be recursive, and you can specify a pattern to be matched in the file contents
