       xonsh - Pythonish, BASHwards looking 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] [--config-path CONFIG_PATH]

              [--rc RC [RC ...]] [--no-rc]  [--no-script-cache]  [--cache-everything]  [-D  ITEM]
              [--timings] [script-file] ...


   positional arguments:
              If present, execute the script in script-file and exit

       args   Additional arguments to the script specified by script-file

   optional arguments:
       -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

       --config-path CONFIG_PATH
              DEPRECATED:  static  configuration  files may now be used in the XONSHRC file list,
              see the --rc option.

       --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.

              What  kind  of  shell  should  be used. Possible options: readline, prompt_toolkit,
              random. 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.
