没人回帖。。。我来个吧

未来的学习之路将是以指数增加的方式增长的。从网管员来说，命令行实际上就是规则，它总是有效的，同时也是灵活的。

笔者五分钟后就给出了解决方法： “首先备份原文件到其他目录，然后删掉/usr/local/unispim/unispimsp.ksc，编辑 /usr/local/unispim/unispimsp.ini，最后重启动计算机

再次，Linux是用C语言编写的，我们有学习C语言的基础，读程序和编写代码方面存在的困难小一点，也是我们能较快掌握的原因之一。?

安装一个新的软件时先看README,再看INSTALL然后看FAQ,最后才动手安装,这样遇到问题就知道为什么。如果Linux说明文档不看,结果出了问题再去论坛来找答案反而浪费时间。

让我树立了很大的信心学好这门课程，也学到了不少专业知识和技能。?
