nushell is a UNIX command line interpreter that replicates core
functionalities of the original Bourne Shell sh.
To use nushell, you have first to clone the project:
$ git clone https://github.com/iamkhalil/nushell.gitThen you've to build it:
$ cd nushell
$ make allYou can now use nushell either in an interactive mode where the shell reads commands from user input on a tty or in a
non-interactive mode via a script or by passing input to nushell via a
pipe.
You can also use make as an interface to run nushell using Valgrind or to run
the test suites.
$ make help
List of available options:
* all - build the project
* test - run the test suites
* memcheck - check memory leaks using Valgrind
* clean - delete build filesBesides basic functionalities including syscalls, nushell does not depend
heavily on the standard library, instead we've created our own custom
functions. As an example, we have created our own getline and strtok to
handle and process user input.
In addition to supporting external programs and handling both absolute and
relative PATHS, nushell has support also for the following features:
