centos下如何获取某个命令的源代码?

以ls命令为例，其它命令类似：

1.利用which命令获取命令可执行文件的位置：

[root@228 /]# which ls

alias ls='ls --color=auto'

    /usr/bin/ls

2.利用rpm命令获取命令所在的安装包：

[root@228 /]# rpm -qif /usr/bin/ls

 * extras: mirrors.tuna.tsinghua.edu.cn

 * updates: mirrors.tuna.tsinghua.edu.cn

coreutils-8.22-21.el7.src.rpm

4.利用rpm2cpio命令提取源代码,得到源码压缩包(coreutils-8.22.tar.xz)：

[root@228 /]# rpm2cpio coreutils-8.22-21.el7.src.rpm | cpio -id

11217 blocks

5.利用xz, tar命令解压即可得命令源代码：

[root@228 /]# xz -d coreutils-8.22.tar.xz

[root@228 /]# tar xvf coreutils-8.22.tar

coreutils-8.22文件夹下即可找到所需要的源代码。
