# Plan to Remove Markdown Tables After First Header in Specified .md Files

## Goal
Remove the markdown table that appears after the first markdown header (## X.Y Title) in 35 specific .md files located in the directory `/Users/rico/src/iso27diy-corp/Corpus/Standards/ISO27x/OST/27002/EN`. These files contain ISO 27002 control descriptions and have a summary table listing Control type, Information security properties, etc., which needs to be removed.

## Analysis
- **Affected Files**: Identified 35 .md files containing the table starting with `| Control type | Information security properties | Cybersecurity concepts | Operational capabilities | Security domains |`.
- **Table Structure**: The table consists of 2-4 lines:
  - Header row starting with `| Control type`
  - Separator row
  - Data row
  - Optionally, an empty row
- **Location**: The table appears immediately after the first `##` header (e.g., `## 8.1 User endpoint devices`) and before the `**Control**` section.
- **Pattern**: All affected files follow the pattern where the table ends just before `**Control**`.

## Approach
Use a Bash script with `sed` to remove the table lines from each affected file. The `sed` command will delete lines from the start of the table (`| Control type`) up to but not including `**Control**`.

### Script
Create and run the following Bash script in the target directory:

```bash
#!/bin/bash

# Change to the target directory
cd /Users/rico/src/iso27diy-corp/Corpus/Standards/ISO27x/OST/27002/EN || exit 1

# Loop through all .md files
for file in *.md; do
  # Check if the file contains the table
  if grep -q "| Control type" "$file"; then
    # Remove the table lines: from "| Control type" to just before "**Control**"
    sed -i '/^| Control type /,/^\*\*Control$/ { /^\*\*Control$/ !d }' "$file"
    echo "Processed $file"
  fi
done

echo "Table removal complete."
```

### Steps to Execute
1. **Navigate to Directory**: Change to `/Users/rico/src/iso27diy-corp/Corpus/Standards/ISO27x/OST/27002/EN`.
2. **Backup (Optional)**: Consider backing up the directory before running the script.
3. **Run Script**: Execute the script to process all files.
4. **Verify**: After running, check a few files (e.g., `a-8.1-User-endpoint-devices.md`, `a-5.15-Access-control.md`) to ensure the table is removed and the `**Control**` section remains intact.

## Risks and Considerations
- **Accuracy**: The `sed` command is designed to precisely target the table based on the observed patterns. If any file has unexpected formatting, manual review may be needed.
- **No Impact on Non-Affected Files**: Files without the table will remain unchanged.
- **Reversibility**: If needed, restore from backup or use version control (assuming the directory is in a git repo).

## Expected Outcome
- Tables removed from 35 files.
- Content before and after the table (including `**Control**` and subsequent sections) preserved.
- No changes to other .md files in the directory.
