join multiple files

onewhoknows · 06-01-2004, 03:34 PM

I have a backup here that I need to join together, but I'm not exactly sure how the process works (sorry if this should be in newbies).

There are 4 files called:
trader-xxxx.bz2
trader-xxxx.bz2.aa
trader-xxxx.bz2.ab
trader-xxxx.bz2.ac

How would I join them to create the original bz2 file? Any help is appreciated!

I use tar and gzip, personally. However, the methodology is similar.

Put them all in a directory, and tar them like this:

tar cvf files.tar your_directory_name

That will tar them all, then you can compress the single tar instance with bz

Well it used to be a single file "trader-xxx.bz2" but someone made a script to split it up into two different ISO files. The two DVDs have those four files, so I want to join them together to make the original trader-xxx.bz2 file.

Would cat work? I guess this really does belong in newbie

Cat should work:
cat trader-xxxx.bz2 > trader-xxxx-full.bz2
cat trader-xxxx.bz2.aa >> trader-xxxx-full.bz2
cat trader-xxxx.bz2.ab >> trader-xxxx-full.bz2
cat trader-xxxx.bz2.ac >> trader-xxxx-full.bz2

cat trader-xxxx.bz2.ac >> trader-xxxx-full.bz2

I used all but the first line, should it still work?

I'm running bunzip2 right now and it seems to be extracting...

Oops, sorry thought you just wanted a compressed single file.

Cat like David said should work great.

I created a seperate file using "full" in the file name but if you cated to the end of file one then it will be fine.

It will not matter - it was just to keep the originals untouched.

You can simplify the command by just typing "cat trader-xxxx.bz2.* > trader-xxxx.bz2"
