It's still in a pretty early state but already provides a very convenient
syntax for flexible execution of external commands from Python.
External commands appear as virtual methods of an object called 'cmd'.
Example:
Python 2.2 (#1, Jan 30 2002, 23:44:31)
[GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from shell.all import *
>>> cmd.ls()
all.py command.py __init__.py
It supports output redirection in the form of iterable commands:
>>> for x in cmd.ls['-l']:
... print 'line:', x
...
line: total 20
line: -rw-rw-r-- 1 oren oren 216 Jun 27 20:49 all.py
line: -rw-rw-r-- 1 oren oren 8259 Jun 27 20:53 command.py
line: -rw-rw-r-- 1 oren oren 136 Jun 27 20:49 __init__.py
Passing the output of one command as arguments to another:
>>> cmd.chmod('+r', cmd.find['.', '-name', '*.html'])
And some other nifty features.
