重定向到STDOUT问题 [英] Redirect to STDOUT Problem
问题描述
尝试做一些相当常规的事情......将输出丢弃到文件中
图，但是bash命令行中的以下命令：
ising output
产生一个闪烁的光标，一个名为output的空文件，和一个永远运行的
程序。没有重定向，输出正常。
下面是用于生成输出的printf语句。
printf（" B =％4.2f E = ％8.4fm =％8.4f Cv =％5.2f \
Chi =％5.2f \ n"，beta，（energy / n2），（moment / n2），\
（summe2-summe * summe）/ n2，\
（summm2-summm * summm）/ n2）;
我验证像''ls output''这样的东西工作得很好，而且我可以
也重定向我写的其他c程序的输出。对于这一个有点儿好笑。
有什么想法吗？
Trying to do something fairly routine... drop output into a file to
graph, but the following command at the bash command line:
ising output
produces a blinking cursor, an empty file named "output," and a
program that runs forever. With no redirect, the output is normal.
Below is the printf statement used to generate output.
printf("B=%4.2f E=%8.4f m=%8.4f Cv=%5.2f \
Chi=%5.2f\n",beta,(energy/n2),(moment/n2), \
(summe2-summe*summe)/n2, \
(summm2-summm*summm)/n2);
I verified that things like ''ls output'' work fine, and that I can
also redirect output from other c programs I''ve written. Something is
funny about this one.
Any thoughts?

在现代系统上，。往往不在你的道路上。您是否忘记了输入./ising的
？
On modern systems, . is often not in your path. Did you just forget
to type ./ising?

这里没有什么可以解释发生了什么。 printf是正确的。
当然，如果n2 == 0你不会得到任何输出但是会发生
有和没有重定向。
Nothing here can explain what is happening. The printf is correct.
Of course, if n2 == 0 you won''t get any output but that will happen
with and without the redirect.
我确认像''ls output''这样的东西工作正常，而我可以
也重定向来自其他c程序的输出我已经书面。这个有点儿好笑。

问题可能不在C代码中。你需要有人看你正在做的事情，他们很可能会立即发现它。我想b / b
认为像comp.unix.programmer这样的团队可能会更好。

The problem is probably not in the C code. You need someone to watch
exactly what you are doing and they''ll probably spot it in no time. I
think a group like comp.unix.programmer might be better.

不，这不是问题。
No, that''s not the problem.

我倾向于同意，但因为*其他所有*除了这个
特定的c程序，其中只包含几个<内部循环和这一个输出语句的
计算，我决定先在这里发布
。
-j
I tend to agree, but since *everything else* works except this
particular c program, which contains nothing more than a few
calculations inside loops and this one output statement, I decided to
post here first.

虽然由于某种原因你决定不发布代码。
仍然，你的损失......

彼得
Though for some reason you decided not to post the code.
Still, your loss...
