发帖数: 28 | 2 Hello!
I want to use multiple data files as input. But, it may be very boring by
input like:
java class1 file1.dat file2.dat ......filen.dat (LONG LIST!!!)
Is it possible to input like : java class1 file*.dat
C++ can do it. How can Java?
Thanks a lot!

It reports an error like this:
cat: /users/test/file3.txt: No such file or directory
it seems it is the redirecting ">" symbol makes problem.
can anyone help here?! thanks. |

发帖数: 8 | 4 I think the easist way is to creat a colletion, either array or list,for
example, filelist to store your all variables, file1...file10, and then use
.....
make sure to save filelist as attribute to any of EL implicit object so EL can access it. |

发帖数: 114 | 5 Hi all,
I want to append new column data to a data file. The data has been formated
in a tabbed way (very clean data without any missing/empty cells). This is
usefull when I run my c/c++ code and save data each time as one or more
columns. Ideally, it will be done within c/c++ code with fstream, but it is
ok to use stript split single (or 2 column) column data into multiple
columns.
e.g.
file1:
1 2 3
2 3 4
5 6 7 |

发帖数: 24 | 11 我有很多个（几百个）文本文件file1,file2,...filem，每个文件中都有100个这样的
字符串，'step n'，n是一个占用8个字符的整数，具体数值不确定，该字符串在所在行
的开头。
我现在需要做这样处理，把文件filem中的每个'step n' 字符串的数字n都替换为数字n
+m*100。我想写shell script来完成，不知道怎么实现，请高手指教。我试了：
sed 's/^step\(.\{8\}\)/step$(\1+500)'
但是不起作用。关键是我只不知道怎么把\1得到的字符串转化为整数，在做计算，不知

其实是很简单的问题。 两个file，一个file有 node1 node2 C 三个field。另一个
file是个lookup table有 node E F三个field。输出是， node1 node2 C E(node1
) F(node1) E(node2) F(node2). 就是为node1,2找对应的E, F然后全部输出的意思
。 可是我不太会写程序，只能写最简单最笨的。 所以我写乐下边这个。 都还没管node2
, 想着先把node1 得E,F输出出来到一个out.txt里边，然后在运行一遍给node2找对应的E
, F。可是因为我的file1很大，几十万条record。 这个程序运行了2个小时乐，才1/5多
点。 可能也是file I/O的问题。 可是如果我不开关file2， 我不知道怎么让file2的
ifstream指针回到文件最顶上。 结果就是他只查找一遍，然 |

I tried the following code.

File2.c
#include
extern int x;
int y = x + 1;
int main() {
printf("x: %d y: %d\n", x, y);
}
If compile with gcc, it gives an error "initializer element is not constant"
. But it compile with g++. I guess in C it's not allow to initialize a
global variable from another variable. So no dependency problem in C.

You can use VirutalDub to split it into 2 files according to
the frame number.
for example: the original file is from frame 0-1211879
save frame 0-1000000 as file1
save frame 1000000-1211879 as file2 |

I have some data files which were originally written with a big_endian
machine.
Now, I try to use a fortran routine to read them with the compiler of
gfortran
built in a little_endian linux system. The input line is as follows:
open(8,file='file1' // cdat,
. form='unformatted',convert='big_endian',
. status='old',access='direct',recl=im*jm*4)
Where cdat is a string, say 198101.
When I compile the routine with gfortran, the system tip is: syntax error,

这样的话我必须把需要用得reference所有的bib文件名都记住。
主要是我想偷懒，每篇文章只要\bibliography{allreference.bib}就可以了。
然后再allreference.bib去引用不同的bib文件。这样我的bib库变化的话我
