    Richard M. Stallman大神是谁就不用说了,一时来了兴趣,想看看Linux系统下有多少程序有这位大神参与编写的。

    先把所有命令导出到文件中,遍历所有命令,用man手册查一下并过滤Stallman关键词。

    以下是脚本

    #!/bin/bash
    i=0;
    touch Stallman
    ls /usr/local/sbin /usr/local/bin /usr/sbin /usr/bin /sbin /bin /usr/games > command
    for line in `cat command`
    do
    	man $line | grep Richard M. Stallman
    	if [ $? -eq 0 ]
    	then
    		i=`expr $i + 1`
    		echo $i $line >> Stallman
    		man $line | grep Richard M. Stallman >> Stallman
    	fi
    done
    
    rm command


    我的系统是Ubuntu11.04的,查找到以下程序。
