Abstract: Shell commands are widely used for accomplishing tasks, such as network management and file manipulation, in Unix and Linux platforms. There are a large number of shell commands available.

A new system, PaSH, has been developed to make computer programs run faster while also delivering accuracy in the Unix shell. The Unix shell is a 50-year-old programming environment that is still ...

Semantics-driven static analysis could be used to improve the safety, correctness, and performance of Unix, Linux, and macOS shell scripts, researchers say. Semantics-driven static analysis is being ...

A new technique can dramatically accelerate programs known as shell scripts, through a process called parallelization, while ensuring the programs return accurate results. Researchers have pioneered a ...
