Cat 2 files together

[ianicr]

Is there another way to cat a file on the end of another file? I've got 5 700mb files that I need in 1. I've done a cat file1 file2 file3 file4 file5 >>new but this takes forever... Is there a quicker way?

 

[Chacalinc]

tar -Af target_file file1 file2 file3 file4

Do some very, very low level programming and change the file inodes directly.

If you manage to do this would you be so kind as to post the code here.

Sorry, it works in linux, what is your unix?

cat concatenates multiple files into a single file.
tar creates an archive file containing multiple files.

the result is not the same.

I'm using cygwin. Tar -Af concatenates files. Not sure if this is any quicker than using cat though...

I you're in a windows environment, you can do

copy /b file1+file2+file3+file4+file5 newfile

ianicr,
cygwin tar (like others) start files into the archive on block bundary.
try this :
tar -Af target_file file

ianicr,
cygwin tar (like others) start files into the archive on block boundary. Before appending a new file to the archive, tar padd the block with null characters.

try this :
tar -Af target_file file1 file2 file3
less target_file
or od -cx target_file

You could try pr

or just run in background

cat file1 file2 >> file3 &
