Dear all

I obtained a file (containing both of number and text) from a program in linux.

I did changes in my file by text editor in windows.

I changed order of the some lines.

for example, before change, the order of lines was as follows:

1
2
3
4
5
.
.
.
.
1000

and now, after the change:

1
2
7
8
3
.
.
.
.
1000.

When I use new file in the my program, I encountered with error (file format is changed and is not standard for program).

But when I compared 2 files (old and new) by text editor in windows, I did not find difference.

One of program developers suggested me to use unix diff tool.

After using following command, diff tool did not give me output file or a text containing information about differences:

diff old.gr new.gro

I attached my files to this e-mail.

Should I use diff by special option?

How to fix this issue?

Please guide me about that.

Any help will highly appreciated.

Best wishes for you.
