The idea: using the Python interpreter as an InteractiveShell.
Use short method names:
1 def S(arg): 2 """returns string of executed command arg""" 3 return os.popen(arg).read() 4 5 def SN(arg): 6 """returns list of executed command arg""" 7 return os.popen(arg).read().split('\n') 8 9 def SP(arg): 10 """prints string of executed command arg""" 11 print S(arg) 12 13 def SNP(arg): 14 """prints with lines list executed command arg""" 15 for i in SN(arg): 16 print i
Command execution is the one thing an InteractiveShell has to be good at. Typing S("<command>") is too much overhead for command execution. Still, a mixture of bash style command execution and shell programming with Python would be great.
I'd want the simple style of command execution from bash available:
But also the Python style for more complex commands:
Some ways to execute the bash-style command:
- Map all commands to Python functions: cd(), less(), all taking a list of strings as arguments.
- Completely separate bash-style commands from Python commands, executing it with bash.

There is a project that attempts to acheive this. Quasi (http://quasi-shell.sourceforge.net/) provides a shell within which Python can be freely mixed with OS (and certain database) commands. -- BenLast
The os.path module provides a good set of functions for path manipulation, but you might also want to split the path at the root:
Simply use the re module. It's a fuller set of regular expressions. Create a wrapper function for a utility for this if you want call it inlinegrep.
The killall function was rejected by the BDFL. As far as I can see from the previous version of this page, Guido rejected it because it isn't in POSIX. I couldn't find any references on this in the mailing list archives. Anyone?
