bill said hi to some chick called Liz. Twice.

Code: [Select]

c:\test> cat *.txt > newfile.txt


We all have gone around the barn instead of directly through the barn.

The following one line by Casper is the solution:

cat *.txt > newfile.txt

or the batch equivilant :

type *.txt > newfile.txt

p.s.  Try it; it works.

I knew I can do it by copy command like: file1.txt+file2.txt.... file all.txt. however it is not efficient way.

OK. Glad to see you got a cool answer.Neat
Now I have a question.
In what way is the more efficient?

I agree copy, cat   and  type are all efficient. 

More than one way to skin a cat.

But there could be other .txt files in the folder.

billrich totally missed the point once again.

[billrich]

But there could be other .txt files in the folder.

dir /s  *.txt or type *.txt or cat *.txt finds all the text (.txt ) files in the folder.

Test the above commands in any folder with text (.txt ) files.

The following code found nothing and/or many duplicates:

@echo off
for /l %%a in (0,1,ENDNUMBER) do type file%%a.txt >> endresult.txt

The Casper code works:

cat *.txt > newfile.txt

The Casper code works:
cat *.txt > newfile.txt

OK. That is True.
What I do not understand is why he ended to put all hte TXT files into one. Any pratical application can get to all the files anyway.
What real application is the out there that has to have all hte TXT files in a directory merged into just one?

I think the right answer is You don't have too!

It is like asking an Eagle if he ...
knows how to hike in to Tuolumne Meadows in Yosemite.


He would say "I don't have too!"

Good point geek. And bill, the op already said that the problem was solved, so I don't understand why there are other solutions that don't function as properly poster after the fact.

no, they are not equivalent. You should try it yourself and see. type will give you the file name as well.

i think he meant that if he has 100 text files, he is not going to type file1+file2+.....file100 on the command line like that. the more convenient way, which i think he missed out,

Code: [Select]

c:\test> copy file*txt output.txt

Casper did nothing wrong by offering  a simple one line solution.  The readers of this board  enjoy more than one solution.

Please thank Casper for his insight:

The Casper code works:
cat *.txt > newfile.txt

Geek,

I have no idea what Netsking, the original poster, intentions are.  

Why does  Netsking, OP, need all the text files in a folder in one large file?

Perhaps for his Boss?

Thanks Ceek for your insight.   A few people understood the problem and the solutions.  It was really quite a simple problem.  Casper showed us the simple solution.

Thanks Casper.

well, if you have not encountered this scenario, it doesn't mean other's won't. Say for example, you have many text log files which you generate each day and its cluttering up your screen when you do dir listings. And they are many years old. Then you might want to concat them according to each month and each year to get rid of these pieces to reduce the amount of files you have. this is just an example, but there certainly are uses for concatenation of files.

Hey bill, try reading next time.

I got it. I rewrite it  as you mentioned. This time it works. Thank you very much for your help.
