Units that measure reciprocal dimensions can be converted (e.g., S to megohm). Parentheses for grouping are supported. This sometimes allows more natural expressions, such as in the example given in Complex units expressions. Roots of units (e.g., sqrt((lbf/inch) / lb) can be computed. Nonlinear units conversions (e.g., °F to °C) are supported.

Sampling profiler for Linux that counts cache misses, stalls, memory fetches, etc.
stat: measure total event count for single program or for system for some time; top: top-like dynamic view of hottest functions; record: measure and save sampling data for single program [13] report: analyze file generated by perf record; can generate flat, or graph profile. [13] annotate: annotate sources or assembly
The proc filesystem (procfs) is a special filesystem in Unix-like operating systems that presents information about processes and other system information in a hierarchical file-like structure, providing a more convenient and standardized method for dynamically accessing process data held in the kernel than traditional tracing methods or direct access to kernel memory.
