btop as a Linux alternative to Process Lasso
Updated
Our verdict
btop can replace Process Lasso for users who need a quick, terminal‑based view of CPU, memory, and process control. It shows real‑time stats, lets you renice or kill processes with shortcuts, and works on any Linux distro. It is best for developers, sysadmins, or power users who prefer a lightweight, cross‑platform tool and do not need Process Lasso’s advanced priority‑auto‑tuning or memory‑throttling features.

What works the same
- Real‑time CPU and memory monitoring
- Process tree view with sorting
- Ability to change process priority (renice) via keyboard
- Export data (CSV)
- Cross‑platform availability (Linux only)
What is different
- No automatic priority or affinity adjustment based on workload
- No CPU/memory throttling or limiting of processes
- No scripting or automation hooks beyond manual shortcuts
- No GUI, only terminal interface
- No support for Windows or macOS
- No integration with system services or background tasks
Opening your Process Lasso files
Process Lasso stores its settings in a proprietary XML file (.plasso). btop has no built‑in importer for this format. To use btop, you would need to manually configure priorities or create a shell script that reads the XML and applies renice/ionice commands. btop can export its own process list to CSV, but that does not replace Process Lasso’s configuration files.
Switching from Process Lasso to btop, step by step
- 1. Install btop from your distro’s package manager (e.g., apt install btop).
- 2. Launch btop with
btopin a terminal to view processes. - 3. Use the renice shortcut (usually
r) to adjust priorities manually. - 4. If you need automated priority changes, write a small shell script that calls
renice/ioniceand run it via cron or systemd. - 5. Export process data with
Ctrl+Eto CSV if you need a record. - 6. Remove or disable Process Lasso from Windows to avoid conflicts.
