This is the most difficult Part I never understand.. But it does the trick! Thanks so much for your help!

It should be exact with 1+2+...+n, that says 55 for n=10 because it is generated by a quantum chemical calculation. If number of numbers are large than 55, then just neglect the numbers in the...

Sorry for my English.
The logic is not complex. if we have a number n, the we have 1+2+3+...+n numbers in the input file separated by comma. the output is formatted as follows if n =10,

1 num1
2...

Hi Singh, thanks for the reply.
It does the job partially because the maximum numbers in one line must be limited to 4. That means the n=1 with 1 number; n=2 with 2; n=3 with 3; n=4 with 4; when n >...

Hi RudiC, thanks for reply.
I think it could be done by a loop combining with awk.
However, I'm not a skillful user with awk.
I have tried for several hours without any progress. The difficulty...

Hello,

I have a huge set of data that needs to be reformatted.
Here is a simple example to explain the process.
I have number n=5 and a input with many numbers separated with comma:

Indeed, I thought about this. What if I have to print the previous m lines before a third pattern? That means it is a mixed process of backward search with pattern 3 and two forward searches with...

Many thanks. You are always come with a super concise, super smart script to solve the problem. May I kindly ask a further question on this problem? How to modified this script if I want to print "2"...

Thanks. I think perl is installed as default with Ubuntu 14. That's already very good to get job done with perl. Is that any possibility to use sed or awk? I suppose either sed or awk should be able...

Hello,

Great! Now, these two rows are aligned within each column. The output is perfectly formatted.
Would you please explain a little bit on 'split', 'sprintf', 'OFS', 'h ORS r'?
How does it work? It's...

Thanks so much for the script. It works like a charm.
Would you please give me some explanation about this script? How does it works so fast. Since you use unformatted print inside awk, so the bond...

Dear friend,

I know for a single case, this could be finished quickly with Excel. But if we have hundreds of files, we definitely want to do it with a script or a FORTRAN code. Since I have no...

Hi guys,

I worked for almost a half-day for the replacement of some text automatically with script. But no success.
The problem is I have hundred of files, which need to be replaced with some...

The whole loop is in a single awk! Great! It's exactly what I expected.

Why only '0' printed...

Sorry for my ambiguous expression. Actually, I want 11 outputs. Each of these outputs will be written to a new file. I could do this within the for loop to prepare 11 outputs. I never know awk could...

Hi Rudic, you are a genius and always write a script with mysterious awk to do the magic things! Where is i? I need to get 11 points from a1 to a2 including a1 when i=0 and a2 when i=1 and other...

because I have no idea how to do this use awk , bash, or python, or fortran.
I know it would be not so hard, but I just tried and I have no clue on this problem.
The main function is to use a...

Dear friends,

I'm wondering if we could do some simple math on two arrays with the same size?
a1

Fe -0.21886700 -0.01417600 -0.24390300
C 2.20529400 ...

Great! I forgot to do it in the beginning! It makes life even more simple! Thanks!

Hi RudiC,

Yes, indeed. I should post this add-up function to that post instead to start a new thread. Can I merged these two threads at this moment?
You are really a great bash programmer!! I...

Hi guys,

I tried to write a script for replacing some number in a bunch of files. However, I failed because my limited bash scripting knowledge.
