Open Source Perl Grep Tools

ldif-extract is a small 'grep' like tool to extract and convert data from LDIF files. It could be used standalone or also in a pipe together with other tools like ldapsearch.

This utility will provide grep-like functionality to return multi-line (record) matches for blank-line deliminated files such as LDIF files used by LDAP. A match on any line will return all lines from the previous blank line until the following one.

Term-Highlight is a highly customizable perl-compatible regexp highlighter for wide range of terminal emulators. Term-Highlight can be used as grep-like engine or command output highlighter. You can use it just to learn perl regular expressions!

greps is a script written in perl which wraps the regular installed grep with new options that can make the search faster and return more relevant results (or less non-relevant results). The usage of greps is same as you would use grep, and all options that are available with grep can be used in the same way also with greps. Basically what greps does is allowing you to choose also the patterns or extentions of relevant files. Then it executes find for finding such files, and executes grep on those files (find | xargs grep).
