bittytop

A tiny, colorful process monitor for your terminal.

Usage

Monitor by Name or PID

Provide one or more names or PIDs as arguments:

# Monitor by name
bittytop firefox

# Monitor by PID
bittytop 1234

# Monitor multiple targets
bittytop pid1 process_name2 5678

System Monitoring

Use * to monitor overall system CPU, Memory, and GPU usage:

bittytop "*"

Interactive Selection

Run without arguments to enter a fuzzy search interface and pick a process:

bittytop

You can also find "SYSTEM" in the search list to monitor overall usage.

Interactive Keys

While monitoring, you can use the following keys:

• c: Toggle CPU usage display
• m: Toggle Memory usage display
• g: Toggle GPU usage display (if available)
• C: Move CPU usage to the primary position
• M: Move Memory usage to the primary position
• G: Move GPU usage to the primary position
• q: Quit

Note: When monitoring specific processes, GPU usage is marked with an orange :G tag (e.g., GPU:G). This indicates it is a global system-wide metric, as per-process GPU tracking is not currently supported.

cargo install --path .
