PaSh is focused on optimizing shell scripts for faster performance in areas around data science, engineering, economists, and more. The apparent Linux Foundation focus is on industrial use-cases.
The Linux Foundation explained in today's announcement , " To accelerate shell scripts, PaSh provides a source-to-source parallelizing compiler, a program that takes as input a programmer’s shell script and returns a new program that is significantly faster than the original program. Since PaSh is source-to-source, it allows the optimized shell script to be inspected and executed using the same tools, in the same environment, and with the same data as the original script. A small runtime library and associated annotations on programs commonly used in shell scripts complete the picture, providing the PaSh compiler with high-performance primitives and supporting its key functions.
