perf

Flame graphs are vital for spotting CPU usage hotspots, particularly in Bash scripts on Linux. These graphs plot the time spent in script segments, helping optimize performance. By using tools like **perf** and **FlameGraph**, developers can visually analyze and refine Bash script efficiency, identifying and addressing performance bottlenecks effectively.

The article, "Unveiling CPU Bottlenecks in Bash Scripts with `perf`", explains how to use `perf` for diagnosing and optimizing CPU usage in Bash scripts. Detailing installation and usage of `perf`, it emphasizes on improving script efficiency by identifying CPU-intensive commands, thus aiding in effective resource utilization.
