Python-powered, cross-platform, Unix-gazing shell.
TLDR

Run commands from a script file and then exit
Define environment variables for the shell process
Load the specified .xonsh or .json configuration files
Skip loading the .xonshrc configuration file
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] ...
xonsh
positional arguments:
- script-file

- -V, --version
Show version information and exit.
- -c COMMAND
Run a single command and exit.
- -i, --interactive
Force running in interactive mode.

- --rc RC [RC ...]
The xonshrc files to load, these may be either xonsh files or JSON-based static configuration files.
- --no-rc
Do not load the .xonshrc files.
- --no-script-cache
Do not cache scripts as they are run.
- --cache-everything
Use a cache, even for interactive commands.
- -D ITEM
Define an environment variable, in the form of -DNAME=VAL. May be used many times.
- --shell-type SHELL_TYPE
What kind of shell should be used. Possible options: b, best, d, dumb, ptk, ptk1, ptk2, prompt-toolkit, prompt_toolkit, prompt-toolkit1, prompt-toolkit2, prompt-toolkit3, prompt_toolkit3, ptk3, rand, random, rl, readline. Warning! If set this overrides $SHELL_TYPE variable.
- --timings
Prints timing information before the prompt is shown. This is useful while tracking down performance issues and investigating startup times.
FILES
The run control file is written in xonsh script and executed once at start-up.
- /etc/xonshrc
System-wide run control file
- ~/.xonshrc
Per-user run control file
In addition to the run control file, a JSON formatted static file can be used to set runtime parameters and environment variables before the xonshrc files are executed.
- $XDG_CONFIG_HOME/xonsh/config.json
Per-user static config file
