Precise DateTime Filters (ISO 8601 format, recommended):

• 2024-07-30T16:00:00,2024-07-30T18:00:00 - Second precision
• 2024-07-30T16:00,2024-07-30T18:00 - Minute precision
• 2024-07-30T16,2024-07-30T18 - Hour precision

# Filter by relative time (no quotes needed)
ccu -t 5min         # Last 5 minutes
ccu -t 2h           # Last 2 hours
ccu -t 7d           # Last 7 days
ccu -t 1m           # Last 1 month
ccu -t 1y           # Last 1 year

# Filter by month range (no quotes needed)

ccu -t july-august  # July to August (current year)

# Filter by date and time (T-separator, no quotes needed)
ccu -t 2024-07-01T14:30:15,2024-07-01T16:45:30  # With seconds
ccu -t 2024-07-01T14:30,2024-07-01T16:45     # With minutes
ccu -t 2024-07-01T14,2024-07-01T16         # With hours

# Filter by specific date range
ccu -t 2024-07-01,2024-08-31
ccu -t 2024-7-2024-8      # July 2024 to August 2024

# Filter by project (partial matching supported)
ccu -p myproject    # Show only messages from projects containing "myproject"

# Combine filters for precise results
ccu -t 1m -p my-website # Last month's my-website project data

📈 Sorting Options

Sort your results by different criteria:

# Sort by cost (highest first)
ccu -s cost -o desc

# Sort by cost (lowest first)
ccu -s cost -o asc

# Sort by total tokens
ccu -s tokens -o desc

# Sort by project name
ccu -s project -o asc

# Sort by time (default)
ccu -s time -o desc

# Combine sorting with filtering
ccu -p my-website -s cost -o desc  # my-website project sorted by cost

🎯 Project Auto-Detection

The tool automatically detects your current project and filters results accordingly:

# When run in a project directory, automatically filters to that project
cd my-project
ccu                     # Shows only my-project usage

# Show all projects explicitly
ccu --all               # Shows usage for all projects
ccu -a

# Manual project filtering still works
ccu -p specific-project # Shows only specific-project usage

📊 View Modes

Switch between different viewing modes:

# Default: aggregated view (by project and date)
ccu

# Detailed view: show individual messages
ccu --detailed
ccu -d

# Comparing views for specific projects
ccu -p my-project       # Aggregated entry for my-project
ccu -p my-project -d    # All individual my-project messages
