ubuntu下所有的快捷方式都在：/usr/share/applications

第1步

创建Pycharm.desktop文件并用gedit的打开

sudo gedit /usr/share/applications/Pycharm.desktop

 第2步

粘贴下面的代码并保存

1. [Desktop Entry]
2. Type=Application
3. Name=Pycharm
4. GenericName=Pycharm3
5. Comment=Pycharm3:The Python IDE
6. Exec=sh /home/xiahuale/download/pycharm-2018.3.3/bin/pycharm.sh
7. Icon=/home/xiahuale/download/pycharm-2018.3.3/bin/pycharm.png
8. Terminal=pycharm
9. Categories=Pycharm

需要修改的2个参数

    Exec的路径是pycharm.sh的所在路径，即pycharm的启动文件

    Icon的路径是pycharm.png的所在路径，即pycharm的图标

第3步

在 /usr/share/applications 目录下找到Pycharm这个文件，复制到桌面

    第4步

修改Pycharm的权限，

在终端中进入 /usr/share/applications 输入命令 

sudo chmod +777 ./Pycharm.desktop

这里777是放开全部权限(可自定义设置)

附带个 Pycharm激活码(我用的时候是好使的)

使用方法

要先修改hosts文件
将0.0.0.0 account.jetbrains.com添加到hosts文件最后，注意hosts文件无后缀，如果遇到无法修改或权限问题，可以采用覆盖的方法去替换hosts文件

在Linux系统中

hosts文件地址：

/etc/hosts

在Windows系统中

一般在下面路径中（64位和32位都一样）

C:\Windows\System32\drivers\etc
