sgrep - Split & Grep

A command-line tool that splits text by regex patterns and filters results by search queries.

Installation

npm install -g split-grep

Usage

<input> | sgrep -r <regex> -s <search_query>

Options

• -r <regex> - Regular expression pattern to split the input text
• -s <search_query> - Search query to filter the split items (case-insensitive)

Examples

Basic Log Filtering

Given a log file with entries starting with [WARN] or [ERROR]:

cat logs.txt | sgrep -r "\n\[" -s "WARN"

This splits the input by newlines followed by [, then returns only items containing "WARN".

Multi-line Entry Filtering

cat logs.txt | sgrep -r "\n\[" -s "someolderror"

Returns complete log entries (including stack traces) that contain the search term anywhere within the entry.

How it Works

1. Split: The input text is split using the provided regex pattern
2. Filter: Each split item is searched for the query string (case-insensitive)
3. Output: Matching items are printed, preserving their original formatting

Use Cases

• Parse and filter log files by log level or error messages
• Extract specific sections from structured text
• Filter multi-line records based on content anywhere in the record
