Usage Examples

Authentication

jdisk auth                    # QR code authentication

Directory Listing

jdisk ls                      # List root directory (simple format)
jdisk ls docs/                # List specific directory
jdisk ls -l                   # Long listing format with details
jdisk ls -lH                  # Long format with human-readable sizes (B, K, M, G)
jdisk ls -lt                  # Sort by modification time (newest first)
jdisk ls -lS                  # Sort by file size (largest first)
jdisk ls -lr                  # Reverse sort order (oldest first)
jdisk ls -a                   # Show all files including hidden (starting with .)
jdisk ls -R                   # Recursive directory listing with tree structure
jdisk ls -lH -t               # Combine options: long format + human sizes + time sort

File Operations

jdisk upload file.txt         # Upload to root directory with progress bar
jdisk upload file.txt docs/   # Upload to specific directory
jdisk download file.txt       # Download from root directory with progress tracking
jdisk download docs/file.txt  # Download from specific directory

Directory Management

jdisk mkdir new_folder        # Create directory
jdisk mkdir -p path/to/nested # Create nested directories (parents created automatically)
jdisk rm file.txt             # Remove file
jdisk rm -r docs/             # Remove directory recursively with confirmation
jdisk mv old.txt new.txt      # Rename file (atomic operation)
jdisk mv file.txt docs/       # Move file to directory (batch move API)

File operations with paths

jdisk upload ./local/file.txt /remote/path/
jdisk download /remote/file.txt ./local/
jdisk ls /folder/subfolder/

Troubleshooting

Authentication Issues

• "QR code expired": Fixed with auto-refresh (QR codes refresh every 50 seconds)
• "Network error": Ensure VPN or campus network connection to SJTU services
• "Session expired": Run jdisk auth to re-authenticate (sessions last 30 minutes)
• "Invalid signature": Restart authentication process and try again

File Operation Issues

• "Upload failed": Check file size (max ~200MB) and network connectivity
• "Download error": Verify file exists and you have download permissions
• "Permission denied": Re-authenticate with jdisk auth to refresh session
• "Move failed": Ensure source file exists and destination path is valid

Performance Issues

• Slow uploads: Check internet speed and try uploading smaller files first
• Connection timeouts: Use stable network connection, avoid WiFi if possible
• Large directory listings: Use specific paths instead of root directory

Common Solutions

• Always run jdisk auth first if you get authentication errors
• Check network connection to SJTU servers (try ping pan.sjtu.edu.cn)
• Verify file paths are correct and use absolute paths starting with /
• Use -p flag with mkdir for creating nested directory structures
• For large file transfers, ensure stable internet connection

Advanced Debugging

# Check session status
ls -la ~/.jdisk/session.json

# Test basic connectivity
curl -I https://pan.sjtu.edu.cn

# Reinstall if needed
uv tool uninstall jdisk && uv tool install jdisk
