bash: __vte_prompt_command: command not found解决办法

     今天不知道做什么操作，只要运行命令就会出现bash: __vte_prompt_command: command not found的提示，根据网上的资料，找到了__vte_prompt_command的出处，即/etc/profile.d，其内容如下：

     记得没有修改这个文件，好像只修改了~/.bashrc这个参数，然后就出现了vte.sh__vte_prompt_command的提示。通过执行source /etc/profile.d/vte.sh即可解决上面的问题，也可把source /etc/profile.d/vte.sh 加入到 ~/.bashrc里面，再执行一下source ~/.bashrc就行了。
