Release - v1.1.0

igrep v1.1.0

Overview

This release fixes a critical issue that prevented the tool from being used out-of-the-box. Previously, igrep required an existing index file to run, making the first launch impossible.

What`s New & Fixed

Added

• create option to initialize new index-files (uses optional --destination flag to set path)
• Optional --source-index flag to index, remove and find options to specify which index-file to use

Fixed

• Improved output formatting by ensuring each line ends with a newline character.

Changed

• Update --help flag output according to new options and flags
