Some simple scripts. For fun / personal use.

Scripts

Simple bash scripts for batch image format conversion:

Usage: ./script_name.sh file1.jpg file2.jpg file3.jpg

rename.sh - Batch rename files with a common prefix
- Prompts for prefix and renames all provided files
- Usage: ./rename.sh file1.txt file2.txt file3.txt

pcap_activity_analyser.py - Analyse PCAP files for network activity patterns
- Groups PCAP files by 24-hour periods based on timestamps in filenames
- Reports on network activity patterns and file sizes
- Can filter for files with unencrypted traffic (requires tshark)
- Supports recursive directory scanning and ZIP creation
- Usage: python3 pcap_activity_analyser.py [options]

A simple script to update the IP address that a Duck DNS domain name resolves to.

$DUCKDNS_DOMAIN: The domain you want to update
$DUCKDNS_TOKEN: The token to use to authenticate the request
$DUCKDNS_IP: (Optional) The IP address that the provided domain should resolve to — Duck DNS will detect and use the source IP otherwise

*All other Duck DNS API options are optional; I'm aiming for feature parity in the future.

NOTE: command line options override environment variables.

Thanks to the folks at Duck DNS for offering such a great service!
