Re: Unarj

[Heikki Vatiainen <hessu@cs.tut.fi>]

I know this problem too. I have even thought about making a wrapper with perl 
to make unarj handle multiple volumes.

Anyways if you have file.arj file.a01 file.a02 etc. you can start by doing 
'unarj x file.arj'. It will uncompress the first part of the big file. Let's 
call the big file 'file.deb'.

You then have to rename 'file.deb' to let's say 'file.tmp'. After that unarj 
the second part, file.a01 and use cat to append the uncompressed part to the 
end of the 'file.tmp'. The command is 'cat file.deb >> file.tmp'. Remove 
'file.deb' and unarj the next archive file.

Do this untill there's no more files to unarj. Here's the whole thing in short:

#unarj x file.arj
#mv file.deb file.tmp
#unarj x file.a01
#cat file.deb >> file.tmp
#rm file.deb
#unarj x file.a02
#cat file.deb >> file.tmp
#rm file.deb
.
.
.

After you have run unarj to all the archive files just use 'mv' to rename the 
reconstructed archive back to it's original name.

This is tedious and takes a lot of extra work but it works. I hope this helps.
