About:
Grepip is a command-line utility designed to filter and extract IPv4 and IPv6 addresses from standard input or files. It mimics the interface of standard grep tools, allowing for seamless integration into existing shell pipelines. This tool simplifies network analysis and log parsing by isolating IP data with high performance.
Key Features:
  • Supports both IPv4 and IPv6 address extraction
  • Grep-compatible command-line interface
  • High-performance processing for large data streams
  • Zero-dependency binary for easy installation
Use Cases:
  • Parsing server access logs to identify unique visitors or suspicious activity
  • Extracting IP addresses from network packet captures or command output
  • Filtering configuration files to validate or audit IP entries
Alternatives:
  • grep -E – Grepip offers pre-configured regex patterns for IPs, reducing syntax complexity and errors.
  • awk/sed – Provides a dedicated, optimized solution instead of requiring custom scripting for IP extraction.
