fortsh is an experimental POSIX-compatible command shell written in modern Fortran. The project explores the feasibility of implementing a practical interactive shell using Fortran while maintaining compatibility with established Unix shell behaviour. It demonstrates that modern Fortran can be used to develop complex system utilities traditionally written in languages such as C.
The shell aims to implement the standard POSIX shell feature set while also supporting a number of commonly used features found in popular shells. fortsh provides an interactive environment for running commands, managing jobs, and navigating the filesystem, making it both a functional shell and an interesting demonstration of modern Fortran capabilities.
This is free and open source software.
