cloudaice / how to use diff
Created February 26, 2012 12:41
linux下面的文本比较命令diff使用
一、文本文件比较命令diff
1>diff命令的功能
Linux中diff命令的功能为逐行比较两个文本文件，列出其不同之处。它对给出的文件进行系统的检查，并显示出两个文件中所有不同的行，不要求事先对文件进行排序。
2>语法
diff [options] file1 file2
该命令告诉用户，为了使两个文件file1和file2一致，需要修改它们的哪些行。如果用”-”表示file1或file2，则表示标准输入。如果file1或file2是目录，那么diff将使用该目录中的同名文件进行比较。

about pagerank
最近我开始学习 Hadoop，本来以为课程应该会更多的侧重如何管理 Hadoop 集群，没想到开始阶段，老师为了让我们更好的理解 Hadoop 的 MapReduce 机制，让我们自己先来实现一个谷歌的 PageRank 算法，本来我想打算使用 Java 来实现的，因为毕竟过段时间，我需要在 Hadoop 集群上部署 Java 代码从而实现数据分析，但我从毕业后就再没用过 Java 写过一行代码，所以我真是写不出来啊，尤其是 PageRank 基本就是矩阵和向量的迭代运算，用 Java 的话一定用到二维数组，我上学的时候学的就不太好。我考虑再三还是决定用 Python 来实现，毕竟上半年的时候自学了一些 Python 语言，而且我知道 Python 有一个第三方模块叫 python-graph，用它来做图论方面的编程容易很多。我是在 Linode VPS 上搭建的 Python 编程环境。相关的模块安装过程如下：
[root@chenjunlu ~]# yum install graphviz*
[root@chenjunlu ~]# yum install vsftpd
[root@chenjunlu ~]# wget http://python-graph.googlecode.com/files/python-graph-core-1.8.2.tar.gz
[root@chenjunlu ~]# tar -zxvf python-graph-core-1.8.2.tar.gz
[root@chenjunlu ~]# cd python-graph-core-1.8.2
[root@chenjunlu ~]# python setup.py install
