zone_from_zips

zone_from_zips.sh

Description

This script searches through a directory of ZIP archives, looks for a specific zone file inside each archive,
and extracts the matching files into a _working/ subdirectory.

Each extracted file is renamed to include both the original zone file name and the archive it came from.

---

Usage

./zone_from_zips.sh <zip_dir> <zone_file_name>

• <zip_dir> → Path to the directory containing ZIP archives
• <zone_file_name> → Exact filename to extract (e.g. db.example.com)

Example:

./zone_from_zips.sh ./exports db.example.com

---

Features

• Processes all .zip or .ZIP files in the given directory (top-level only).
• Extracts only the specified <zone_file_name> from each archive.
• Saves results in:

  <zip_dir>/_working/
  

• Renames extracted files to:

  <zone_file_name>_<archive_basename>
  

  Example: db.example.com_backup1.zip → db.example.com_backup1.

---

Output

• Extracted files:

  <zip_dir>/_working/<zone_file_name>_<archive-name>
  

• Console log:
  • Reports each archive processed
  • Indicates whether the zone file was found

---

Requirements

• Bash
• unzip

---

Notes

• If no .zip files are found, the script exits with an error.
• Only files in the top level of <zip_dir> are processed (not recursive).
• Existing _working/ directory will be reused (files may be overwritten).
