XONSH

NAME

xonsh - Pythonish, BASHwards looking shell

DESCRIPTION

Xonsh is a Python-ish shell language and command prompt. Unlike other shells, xonsh is based on Python, with additional syntax added that makes calling subprocess commands, manipulating the environment, and dealing with the file system easy. Xonsh supports all normal Python constructs and a subset of those available in bash.

usage: xonsh [-h] [-V] [-c COMMAND] [-i] [-l] [--rc RC [RC ...]] [--no-rc]

[--no-script-cache] [--cache-everything] [-D ITEM] [--shell-type SHELL_TYPE] [--timings] [script-file] ...
