如何经过apt-get得到安装包的源码

有时候咱们须要得到某个可执行程序的源码，而不单单是一个可执行程序，好比咱们想获取tree这个工具的源码，这时候就能够采用下面的命令：

 

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

执行完成以后，就会在当前目录生成以下几个文件：

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

其中目录tree-1.6.0中就是想要的tree的源码了，根据其中的提示能够手工编译生成目标机器上的tree命令。
