Xonsh
From wikinotes
Xonsh is kind of neat, and I like it a lot for complex manipulation of files. It meets halfway between shellscript and python
Usage
## example use-case: renaming ripped episodes from glob import glob files = glob('*.mkv') for i in range(len(files)): filename = sorted(files)[i] mv @(filename) @('SE02E'+ str(i+10).zfill(2)) ...
Configuration
~/.xonshrcconfig file http://xon.sh/envvars.html?highlight=vi_mode environment variables that can be set to modify xonsh
vi mode
env VI_MODE=1 xonsh
Aliases
Aliases, in xonsh are stored in a dictionary.
## Example print( aliases ) >>> 'ls': ['ls', '--color=auto'], >>> 'grep': ['grep', '--color=auto'], >>> ...Setting aliases is done similarly:
aliases['ll'] = ['ls', '-l']
Syntax
Environment
Xonsh works within a few different environments (generally determined by the command first issued on the line, and whether it looks like a command, or a python-command).
@( ) # within bash-mode, anything executed between these brackets will be from the python env ${ } # ? $HOME # environment variables within python-mode
