你把cat -n yourcodefile打出来的结果给贴出来巴
这样看太费劲了。

tahaomei · 发表于 2007-1-22 10:52:32

已经将格式转换了，你再看看吧

Iambitious · 发表于 2007-1-22 10:53:16

找到毛病了把“$x”改成$x
你要判断的是整数不是字符串.

tahaomei · 发表于 2007-1-22 10:55:09

好的，我试下看

tahaomei · 发表于 2007-1-22 10:58:10

不行啊，还是这个问题

Iambitious · 发表于 2007-1-22 11:01:33

看chinaunix版,你问的问题.

tahaomei · 发表于 2007-1-22 11:16:25

刚才在chinaunix找到原因了，是应该是`expr $x + 1`要有空格.

但是又出现如下问题

我先将我的全部源代码给出来

现在就 98 ### collect adsorption amount, isosteric heat, et al. as column data
这部分代码有问题，执行完后，一直不出现那个“Done”，然后在/export/home/pengx/testsh/results目录下，只有一个rho.txt文件，文件大小不断增大，也就是说一直在写入数据到rho.txt文件中，该文件内容如下：

w,0.3549nm w,0.7098nm
p,kpa rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho rho

请问该如何调试？

Iambitious · 发表于 2007-1-22 11:29:00

在while循环中没有更新x的值，死循环。

该如何修改呢？

我现在都不愿意动脑了，边学边写，实在太累了

Iambitious · 发表于 2007-1-22 11:36:35

while [ $x -lt 6 ]
121                   do
122                      printf "%-20s" "${i}" >> ${i}.txt
123                   done
比如对于这个while循环，不断地测试x是否小于6，由于在循环体中没有更新x的值，所以x 一直小于6，所以死循环，至于具体怎么改，你应该问你自己想要这个循环干什么。还有边学边写虽然累，但是也学到的最扎实，我很羡慕你有这样的环境，像我所做的项目与bash基本不相关，所以我只能在论坛上看别人提出的问题，然后自己试一试,这样很难提高。
