Petalinux建立工程时出现WARNING: /bin/sh is not bash!的解决方法

出现（WARNING: /bin/sh is not bash!)如何解决

在运行命令：

@ubuntu$:source /opt/pkg/petalinux/settings.sh`

`
时候出现以下内容：

PetaLinux environment set to '/opt/pkg/petalinux'
WARNING: /bin/sh is not bash! 
bash is PetaLinux recommended shell. Please set your default shell to bash.
INFO: Checking free disk space
INFO: Checking installed tools
INFO: Checking installed development libraries
INFO: Checking network and other services

重装了一遍Petalinux并不能解决问题，在试了几个方法后发现是shell没有更改成bash，输入以下命令即可解决：

sudo dpkg-reconfigure dash

重新测试，输入命令：

source /opt/pkg/petalinux/settings.sh

成功提示：
PetaLinux environment set to ‘/opt/pkg/petalinux’
INFO: Checking free disk space
INFO: Checking installed tools
INFO: Checking installed development libraries
INFO: Checking network and other services

安装成功~

另外今天刚学到的如何一个命令实现ubuntu和win10之间进行文字的复制粘贴：
直接在终端输入：

vncconfig -nowin&

就可以实现复制粘贴啦（不要关闭终端噢，关闭了就失效了）~~
