ubuntu18.10终端的方块改成竖线

参考了国外的链接
https://stackoverflow.com/questions/4416909/anyway-change-the-cursor-vertical-line-instead-of-a-box

解决方案如下：

在~/.bashrc中的末尾添加下面的句子：

echo -e -n "\x1b[\x30 q" # changes to blinking block
echo -e -n "\x1b[\x31 q" # changes to blinking block also
echo -e -n "\x1b[\x32 q" # changes to steady block
echo -e -n "\x1b[\x33 q" # changes to blinking underline
echo -e -n "\x1b[\x34 q" # changes to steady underline
echo -e -n "\x1b[\x35 q" # changes to blinking bar
echo -e -n "\x1b[\x36 q" # changes to steady bar

然后重新开一个终端就可以了。
