Assuming I define a trivial task to list files on a remote server:
假设我定义了一个简单的任务来列出远程服务器上的文件:
from fabric.api import run, env
env.use_ssh_config = True
def list_files():
run('ls')
And I execute it with:
我执行它:
fab -H server list_files
How can I specify the working directory for the command I'm running, other than doing:
如何为我正在运行的命令指定工作目录,而不是:
run('cd /tmp && ls')
Which doesn't look very idiomatic to me?
哪个对我来说不是很惯用?
Disclaimer: I'm looking at Fabric for the first time in my life and I'm totally new to Python.
免责声明:我在生活中第一次看到Fabric,而且我对Python完全不熟悉。
