方法一：
搜索nautilus-open-terminal安装
命令行：sudo apt-get install nautilus-open-terminal (如果提示为找的什么的就sudo apt-get update&&sudo apt-get upgrade)
重新加载文件管理器
nautilus -q
或注销再登录即要使用
方法二：
进入主目录的.gnome2/nautilus-scripts目录。新建一个文件，文件名任意（这个文件名会显示
在右键菜单里，最好是通俗易懂的，比如“打开终端”或“open-terminal”），文件内容如下。
#!/bin/bash
# This script opens a gnome-terminal in the directory you select.
# Distributed under the terms of GNU GPL version 2 or later
# Install in ~/.gnome2/nautilus-scripts or ~/Nautilus/scripts
# You need to be running Nautilus 1.0.3+ to use scripts.
# When a directory is selected, go there. Otherwise go to current
# directory. If more than one directory is selected, show error.
if [ -n "$NAUTILUS_SCRIPT_SELECTED_FILE_PATHS" ]; then
set $NAUTILUS_SCRIPT_SELECTED_FILE_PATHS
if [ $# -eq 1 ]; then
destination="$1"
# Go to file's directory if it's a file
if [ ! -d "$destination" ]; then
destination="`dirname "$destination"`"
fi
else
zenity --error --title="Error - Open terminal here"
--text="You can only select one directory."
exit 1
fi
else
destination="`echo "$NAUTILUS_SCRIPT_CURRENT_URI" | sed 's/^file:////'`"
fi
# It's only possible to go to local directories
if [ -n "`echo "$destination" | grep '^[a-zA-Z0-9]+:'`" ]; then
zenity --error --title="Error - Open terminal here"
--text="Only local directories can be used."
exit 1
fi
cd "$destination"
exec x-terminal-emulator
添加完后，把此文件加上可执行的权限。
chmod +x 文件
以上只是总结的别人的方法，方便自己使用。
