搜索了这个，似乎找不到已经问过的人，所以这里是。

我开始切换到 IPython 作为我在 Windows 7 上的首选 shell，我想对其进行配置，以便 bang magic ( !cmd ) 将命令传递给系统 shell 使用 PowerShell 而不是 cmd .exe，这样我就可以利用 MS 所做的改进，而不必更改我的 %COMSPEC%到 PowerShell(我的公司仍然使用几个基于 CMD 的 .BAT 来实现自动化，我不想破坏它们)。

我会在顶部发布我的问题，因为答案可能不需要以下任何信息:

[PS] C:\> $env:comspec

最佳答案

您可以使用 IPython 的脚本魔法来执行 PowerShell 命令。

定义魔法

在您的 IPython profile , 修改 ipython_config.py包括以下行:

c.ScriptMagics.script_magics = ['powershell']
c.ScriptMagics.script_paths = {
        'powershell':'powershell.exe -noprofile -command -'}

In [1]: %%powershell
   ...: 1..5
1
2
3
4
5

from IPython.core.magic import register_line_cell_magic

from IPython import get_ipython
ipython = get_ipython()

@register_line_cell_magic
def ps(line, cell=None):
    "Magic that works both as %ps and as %%ps" 
    if cell is None:
        ipython.run_cell_magic('powershell', '--out posh_output' ,line)
        return posh_output.splitlines()
    else:
        return ipython.run_cell_magic('powershell', line, cell)

In [1]: ps_version = %ps $PSVersionTable.PSVersion.ToString()

In [2]: print(ps_version)
['2.0']

In [3]: %%ps
   ...: gci c:\

    Directory: C:\

In [4]: %%ps --out process_name_id
   ...: $procs = gps| select Name, ID
   ...: $procs| ConvertTo-Csv -NoType| select -skip 1

In [5]: import csv

In [6]: list(csv.reader(process_name_id.splitlines()))
