Linux问题

1.Makefile

mkdir -p build/{bin/,certs/,db/,scripts/,log/}

Linux command：mkdir -p build/{bin,certs,db,scripts,log}

2.sudo apt-get install

ubuntu常见错误--Could not get lock /var/lib/dpkg/lock解决

通过终端安装程序sudo apt-get install xxx时出错：

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it

出现这个问题可能是有另外一个程序正在运行，导致资源被锁不可用。而导致资源被锁的原因可能是上次运行安装或更新时没有正常完成，进而出现此状况，解决的办法其实很简单：

在终端中敲入以下两句

sudo rm /var/cache/apt/archives/lock

sudo rm /var/lib/dpkg/lock
