need help: How to write a batch to combine more 100 text files to one text file?

[netsking]

Hi, there,

I am new comer in here.
Could anybody help me to write a batch to combine more than 100 text files to one text file?
I knew I can do it by copy command like: file1.txt+file2.txt.... file all.txt. however it is not efficient way.
Thanks a lot in advance.

Are the files all sequential? Are the names basically the same? Are they in the same location? Can you give a list of SOME of the names?

[netsking]

Yes. They are all in the same directory and the file names are sequential.

[Helpmeh]

Put this in a batch file.

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

That should do it.

Put this in a batch file.

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

That should do it.

I make a batch file like:

@echo off
for /l %%a in (0,1,50)
songci_%%a.txt>>endresult.txt

the file name is songci_#.txt,
But run this batch, nothing happened. I am freshman. Could you tell me more? Thanks a lot.

@echo off
for /l %%a in (0,1,50) do type songci_%%a.txt >> endresult.txt
That should work.

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

Write a batch to combine more than 100 text files to one text file?

C:\batch\backup>type  combine.bat

Code: [Select]

@echo off
echo. > c:\tmp2\endresult.txt
cd c:\batch\backup\

for /f %%a in ('dir /b  *.txt') do type %%a >> c:\tmp2\endresult.txt

echo  type  endresult.txt

type c:\tmp2\endresult.txt
C:\batch\backup>

OUTPUT:

C:\batch\backup>combine.bat
 type  endresult.txt

 hello liz
 hello liz


C:\batch\backup>

note that by adding more switches  to dir /b you can govern the order in which the files are added

Code: [Select]

/O          List by files in sorted order.
 sortorder    N  By name (alphabetic)       S  By size (smallest first)
              E  By extension (alphabetic)  D  By date/time (oldest first)
              - Prefix to reverse order
the case does not matter.

for example dir /b /on would sort by name a - z and dir /b /o-n would sort z - a

C:\batch\backup>type  combine.bat

Code: [Select]

@echo off
echo. > c:\tmp2\endresult.txt
cd c:\batch\backup\

for /f %%a in ('dir /b  *.txt') do type %%a >> c:\tmp2\endresult.txt

echo  type  endresult.txt

type c:\tmp2\endresult.txt
C:\batch\backup>

OUTPUT:

C:\batch\backup>combine.bat
 type  endresult.txt

 hello liz
 hello liz


C:\batch\backup>

The problem was solved. We've made a dollar already, so we don't need the extra $0.10.

if you can, download GNU tools(see my sig) and use cat

Code: [Select]

c:\test> cat file*txt > newfile.
that's it.

Casper had a better way:

"Download GNU tools(see my sig) and use cat

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

We saw no output for:

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

Will it work?  You must modify ENDNUMBER  each time the program is run?

Casper's  code and my code are much better.  We showed  the output. Proof the code works.

bill, you may only have a small b in your "name", and not a big one, these days, but man you sure are a *censored*.
