How to Monitor Stock Prices from Ubuntu Command Line Using Mop
================================================================================
Having a side income is always good, especially when you can easily manage the work along with your full time job. If your regular work involves working on an Internet-connected computer, trading stocks is a popular option to earn a few extra bucks.
While there are quite a few stock-monitoring applications available for Linux, most of them are GUI-based. What if you’re a Linux professional who spends a lot (or all) of your time working on machines that do not have any GUI installed? Are you out of luck? Well, no, there are some command line stock-tracking tools, including Mop, which we’ll be discussing in this article.
### Mop ###
Mop, as already mentioned in the introduction above, is a command line tool that displays continuous and updated information about the US stock markets and individual stocks. Implemented in the GO programming language, the project is the brain child of Michael Dvorkin.
### Download and Install ###
Since the project is implemented in GO, before installing the tool, you’ll first have to make sure that the programming language is installed on your machine. Following are the steps required to install GO on a Debian-based system like Ubuntu:
sudo apt-get install golang
mkdir ~/workspace
echo 'export GOPATH="$HOME/workspace"' >> ~/.bashrc
source ~/.bashrc
Once GO is installed, the next step is to install the Mop tool and set the environment, something which you can do by running the following commands:
sudo apt-get install git
go get github.com/michaeldv/mop
cd $GOPATH/src/github.com/michaeldv/mop
make install
export PATH="$PATH:$GOPATH/bin"
Once done, just run the following command to execute Mop:
cmd
### Features ###
When you run the Mop command for the first time, you’ll see an output similar to the following.

As you can see in the image above, the output – which auto-refreshes frequently – contains information related to various popular stock exchanges around the world as well as individual stocks.
### Add/remove stocks ###
Mop allows you to easily add/remove individual stocks to and from the output list. To add a stock, all you have to do is to press “+” and mention the stock listing name when prompted. For example, the following screenshot was taken while adding Facebook (FB) to the list.
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-add-stock.png)
As I pressed the “+” key, a row containing text “Add tickers:” appeared, prompting me to add the stock listing name – I added FB for Facebook and pressed Enter. The output refreshed, and the new stock was added to the list:

Similarly, you can delete a stock listing by pressing “-” and mentioning its name.
#### Group stocks based on value ####
There is a way to group stocks based on whether their value is going up or down – all you have to do is to press the “g” key. Following this, the stocks which are advancing will be grouped together and shown in green, while those whose value is going down will be represented in black.
Here is an example screenshot.

#### Column sort ####
Mop also allows you to change the sort order of individual columns. For this you first need to press “o” (this will select the first column by default), and then use the left and right arrow keys to select the column you want to sort. Once done, press enter to sort the column contents.
For example, the following screenshot shows the output after the contents of the first column were sorted in descending alphabetical order.

**Note**: to better understand, compare it with the previous screenshot.
#### Other options ####
Other available options include “p” for pausing market data and stock updates, “q” or “esc” for quitting the command line application, and “?” for displaying the help page.

### Conclusion ###
Mop is a basic stock monitoring tool that doesn’t offer a plethora of features, but does what it promises. It’s quite obvious that the tool is not for stock trading professionals but is still a decent choice if all you want to do is some basic stock tracking on a command line-only machine.

命令行下使用Mop 监视股票价格
================================================================================
有一份隐性收入通常很不错，特别是当你可以轻松的协调业余和全职工作。如果你的日常工作使用了联网的电脑，交易股票是一个很流行的选项来获取额外收入。
但是目前只有很少的股票监视软件可以用在linux 上，其中大多数还是基于图形界面的。如果你是一个Linux 专家，并且大量的工作时间是在没有图形界面的电脑上呢？你是不是就没办法了？不，这里还有一个命令行下的股票追踪工具，包括Mop，也就是本文要聊一聊的工具。
### Mop ###
Mop，如上所述，是一个命令行下连续显示和更新美股和独立股票信息的工具。使用GO 实现的，是Michael Dvorkin 大脑的产物。
### 下载安装 ###
因为这个工程使用GO 实现的，所以你要做的第一步是在你的计算机上安装这种编程语言，下面就是在Debian 系系统，比如Ubuntu上安装GO的步骤：
sudo apt-get install golang
mkdir ~/workspace
echo 'export GOPATH="$HOME/workspace"' >> ~/.bashrc
source ~/.bashrc
GO 安装好后的下一步是安装Mop 工具和配置环境，你要做的是运行下面的命令：
sudo apt-get install git
go get github.com/michaeldv/mop
cd $GOPATH/src/github.com/michaeldv/mop
make install
export PATH="$PATH:$GOPATH/bin"
完成之后就可以运行下面的命令执行Mop：
cmd
### 特性 ###
当你第一次运行Mop 时，你会看到类似下面的输出信息：
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-first-run.jpg)
如你所见，这些输出信息—— 周期性自动刷新 ——包含了主要几个交易所和个股的信息。
### 添加删除股票 ###
Mop 允许你轻松的从输出列表上添加/删除个股信息。要添加，你全部要做的是按”+“和输入股票名称。举个例子，下图就是添加Facebook (FB) 到列表里。
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-add-stock.png)
因为我按下了”+“键，一列包含文本”Add tickers：“出现了，提示我添加股票名称—— 我添加了FB 然后按下回车。输出列表更新了，我添加的新股票也出现在列表了：
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-stock-added.png)
类似的，你可以使用”-“ 键和提供股票名称删除一个股票。
#### 根据价格分组 ####
还有一个把股票分组的办法：依据他们的股价升跌，你索要做的就是按下”g“ 键。接下来，股票会分组显示：升的在一起使用绿色字体显示，而下跌的股票会黑色字体显示。
如下所示：
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-group-stocks-profit-loss.png)
#### 列排序 ####
Mop 同时也允许你根据不同的列类型改变排序规则。这种用法需要你按下”o“（这个命令默认使用第一列的值来排序），然后使用左右键来选择你要使用的列。完成之后按下回车对内容重新排序。
举个例子，下面的截图就是根据输出内容的第一列、按照字母表排序之后的结果。
![](https://www.maketecheasier.com/assets/uploads/2015/09/mop-change-order.png)
**注意**: 为了更好的理解，和前面的截屏对比一下。
#### 其他选项 ####
其它的可用选项包括”p“：暂停市场和股票信息更新，”q“ 或者”esc“ 来退出命令行程序，”？“ 显示帮助页。

### 结论 ###
Mop 是一个基础的股票监控工具，并没有提供太多的特性，只提供了他声称的功能。很明显，这个工具并不是为专业股票交易者提供的，而仅仅为你在只有命令行的机器上得体的提供了一个跟踪股票信息的选择。
