Python-powered, cross-platform, Unix-gazing shell.
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] ...
If present, execute the script in script-file and exit.
Additional arguments to the script specified by script-file.
- -h, --help
Show help and exit.
- -V, --version
Show version information and exit.
- -c COMMAND
Run a single command and exit.
- -i, --interactive
Force running in interactive mode.
- -l, --login
Run as a login shell.
- --rc RC [RC ...]
The xonshrc files to load, these may be either xonsh files or JSON-based static configuration files.
Do not load the .xonshrc files.
Do not cache scripts as they are run.
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.
Prints timing information before the prompt is shown. This is useful while tracking down performance issues and investigating startup times.
The run control file is written in xonsh script and executed once at start-up.
System-wide run control file
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.
