npm install package-name
git clone https://github.com/user/repo.git
cd repo
pip install -e .
### Troubleshooting Section
```markdown
## Troubleshooting
### Error: "Module not found"
**Cause:** Package not installed or wrong Python environment
**Solution:**
```bash
pip install package-name
Cause: Insufficient file permissions
Solution:
sudo command
# or
chmod +x script.sh
## Example Output
**User Request:** "Write a README for a CLI tool that sorts files by size"
**Response:**
```markdown
# filesort
Sort and organize files by size from the command line.
## Features
- Sort files in any directory by size
- Filter by file extension
- Export results to CSV
- Human-readable size formatting
## Installation
```bash
pip install filesort
Sort files in current directory:
filesort .
Output:
1.2 GB video.mp4
856 MB dataset.zip
45 MB photo.jpg
2.1 KB README.md
filesort [OPTIONS] DIRECTORY
| Option | Description |
|---|---|
-r, --reverse |
Show largest files first (default: smallest first) |
-n, --number NUM |
Show only top N files |
-e, --extension EXT |
Filter by file extension |
-o, --output FILE |
Export to CSV file |
--recursive |
Include subdirectories |
Find your 10 largest files:
filesort . --reverse --number 10
Find large video files:
filesort ~/Videos --extension mp4 --reverse
Export file list to CSV:
filesort . --output files.csv
Search recursively:
filesort ~/Documents --recursive --reverse --number 20
Create ~/.filesort.yaml for default options:
reverse: true
number: 50
ignore:
- "*.tmp"
- "__pycache__"
Some directories require elevated permissions:
sudo filesort /var/log
Check if you're filtering too aggressively:
# This might not match anything
filesort . --extension xyz
# Try without filters
filesort .
