向终端输出命令？ [英] outputting a command to the terminal?
问题描述
这是我的新项目：我想写一个小脚本，我可以在终端输入
，如下所示：
$ scriptname package1 [package2，...]
其中scriptname是我的模块名，任何后续参数都是要安装的Linux软件包的
名称。运行上面的脚本将
创建这一行：
sudo aptitude install package1 package2 ...
它将在终端运行该行，以便安装包。
现在，我想要添加的额外功能（否则我只会
正常安装它们！）是将包名保存到文本文件中所以我现在可以手动安装程序的名称，如果我想要
检查列表或删除包。
所以创建正确的bash命令（sudo aptitude install ...）很简单，
并编写名称到文件很容易。但是我有两个问题：
1.首先，Linux是否会手动跟踪您的软件包
安装？如果是这样，那么我根本不需要这样做。
2.假设我写这个，如何输出bash命令到
终端？是否有一个Python用来与之交互的特定模块
我可以用来将安装命令发送到
终端的终端窗口？
谢谢。
Here''s my new project: I want to write a little script that I can type
at the terminal like this:
$ scriptname package1 [package2, ...]
where scriptname is my module name and any subsequent arguments are the
names of Linux packages to install. Running the script as above will
create this line:
sudo aptitude install package1 package2 ...
It will run that line at the terminal so the package(s) will be installed.
Now, the extra functionality I want to add (otherwise I would just
install them normally!) is to save the package names to a text file so I
can now the names of programs I''ve manually installed, if I ever want to
check the list or remove packages.
So creating the proper bash command (sudo aptitude install ...) is easy,
and writing the names to a file is easy. But I have two questions:
1. First of all, does Linux keep track of the packages you manually
install? If so, then I won''t have to do this at all.
2. Assuming I write this, how do output the bash command to the
terminal? Is there a particular module that Python uses to interact with
the terminal window that I can use to send the install command to the
terminal?
Thanks.

你没有把命令交给终端。 shell执行命令。
但它主要只是一个程序本身 - 它可以产生子进程和
使它们执行实际的命令。所以 - 您需要的模块最多可能是子流程。

You don''t put a command to the terminal. The shell executes commands.
But it is mainly just a program itself - it can spawn subprocesses and
make these execute the actual commands. so - the module you need is most
probably subprocess.
