Ubuntu14.04增加右键菜单=>“run_on_python”

运行python程序总是要打开终端，cd到目录，输入python $file，真的很麻烦，找了一下资料，发现如下：

• 在/home/ydf/.local/share/nautilus/scripts/文件夹下新建run_on_python和run_on_python_helper文件，内容如下：

# run_on_pythongnome-terminal -e "expect /home/ydf/.local/share/nautilus/scripts/run_on_python_helper $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS"

# run_on_python_helper#!/usr/bin/expect -f# Get a Bash shellspawn -noecho bash# Wait for a promptexpect "$ "set file [lindex $argv 0]# Type somethingsend "python $file\n"# Hand over control to the userinteractexit

• 给run_on_python文件增加可执行权限：右键=>Properties=>Permissions=>Allow executing as files as program。

• 建立测试文件：lalala.py，内容如下：

import timefor i in range(10):    print 'klalala'    time.sleep(1)

• 右键lalala.py=>Scripts=>run_on_python，即可看到效果了。
