Linux問題

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常見錯誤--Could not get lock /var/lib/dpkg/lock解決

經過終端安裝程序sudo apt-get install xxx時出錯：

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

出現這個問題多是有另一個程序正在運行，致使資源被鎖不可用。而致使資源被鎖的緣由多是上次運行安裝或更新時沒有正常完成，進而出現此情況，解決的辦法其實很簡單：

在終端中敲入如下兩句

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

sudo rm /var/lib/dpkg/lock
