+#!/bin/bash
+
+# This script extracts files changed between two specified Git commit IDs and performs various file operations.
+# Usage:
+# 1. Make sure this script is executable: `chmod +x ./scripts/diff.sh`
+# 2. Run the script: `./scripts/diff.sh`
+# 3. The script will prompt you to enter two commit IDs.
+#    - `commit_id_from` (inclusive): The starting commit ID for the diff operation.
+#    - `commit_id_to`: The ending commit ID for the diff operation.
+# 4. The script will create a tarball of the changed files, extract them, and organize them into specified directories.
+# 5. It will then move PDF and SVG files to separate directories and open these directories.
+# 6. Finally, it will list files with more than 3 lines.
+
+# Note:
+# - Commit IDs can be obtained using `git log` to view the commit history.
+# - The script assumes it is located in a `scripts` directory relative to the Git repository.
+
+# Prompt the user for the commit IDs
+read -p "Enter the commit ID from (inclusive): " commit_id_from
+read -p "Enter the commit ID to: " commit_id_to
+
+# Run the git diff-tree command with the user-provided commit IDs and pipe the result to tar
+git diff-tree -r --no-commit-id --name-only --diff-filter=ACMRT ${commit_id_from}^..${commit_id_to} | tar -czf ../assets.tgz -T -
