When I feel like scrapping the whole project and starting over:
Me: (in the project dir) sudo rm -rf /*
Me: (after waiting a while) Something feels off… Why is it taking so long to delete everything?
Me: (suddenly realizing) ^C ^C ^C
System: Press any key to continue…
当我想把整个项目推倒重做时：
我:（在项目目录）sudo rm -rf /*
我:（等了一会儿）有点不对劲。。。怎么删了这么长时间还没删完
我:（恍然大悟）^C ^C ^C
系统： Press any key to continue…
mv folder delete-this rm -rf delete-thisgives you one chance to reconsider what you just did before it is too late. And you never have a risk of a dangerous delete-all lurking in your command history.
