如何經過apt-get得到安裝包的源碼

有時候咱們須要得到某個可執行程序的源碼，而不單單是一個可執行程序，好比咱們想獲取tree這個工具的源碼，這時候就能夠採用下面的命令：

 

sudo apt-get source tree

 

pengdl@debian:~$ sudo apt-get source tree Reading package lists... Done Building dependency tree Reading state information... Done NOTICE: 'tree' packaging is maintained in the 'Git' version control system at: git://git.debian.org/collab-maint/tree.git

執行完成以後，就會在當前目錄生成以下幾個文件：

tree-1.6.0
tree_1.6.0-1.dsc
tree_1.6.0-1.debian.tar.gz
tree_1.6.0.orig.tar.gz

其中目錄tree-1.6.0中就是想要的tree的源碼了，根據其中的提示能夠手工編譯生成目標機器上的tree命令。
