help with zip

[Jux]

ok this is not a knoppix subject but rather a basic linux topic. I am a type of newb who doesent get what --help and man tries to say - so maybe u can help me.

i want to do a simple stuff.

create a archive of one file to smaller zip-part files.

Input: file.exe (3mb)
zip rizzledizzle
Output: archive1.zip(1mb); archive2.zip(1mb); archive3.zip(0.5mb)

Hopu u understand what i mean - and pleas tell me the line i have to type to terminal.

thnx

I believe zip doesn't support volume spanning (at least not UNIX zip). Use rar/unrar instead, it comes with Debian and is supported on Windows too (by WinRAR).

right now i am at work and here we have one redhat version from ancient history and it has onli tar and zip - so is it possible with tar?
how?

thnx

It's possible, yes, but I have never done it. :)
You can't use compression (ie tar.gz, tar.bz2, etc) with multivolume tar archives though.

I have no floppy disk here so this is a wild guess:

tar Mcvf /floppy/newarchive.tar *

This - I *think* - would create newarchive.tar on the floppy (if mounted on /floppy) with all files in the current directory, and hopefully pause and ask you for a new medium (disk) when it runs out of space.

--Here's something I thought of trying with zip, but I dunno if such an old RH will support it:

(example)

' zip -9q rizzledizzle /boot/* '

-rw-r--r-- 1 dave dave 3497680 Sep 17 19:54 rizzledizzle.zip


( The number below is 1400 * 1024 )


' zipsplit -b . -n 1433600 rizzledizzle.zip '

3 zip files will be made (100% efficiency)
creating: ./rizzled1.zip
creating: ./rizzled2.zip
creating: ./rizzled3.zip

--The PROBLEM is, I think zipsplit can't break up a zip into arbitrary sizes - it can only start a new zipfile where the internal filesizes are small enough that an EOF is encountered, and adding another file will overflow the desired size. In other words, it won't work on just 1 big file.

(Turns out my suspicion is right: )


' zip -9q rizzledizzle /mnt/drived/dave/Installed/spybotsd12.exe '

' zipsplit -b . -n 1433600 rizzledizzle.zip '
zipsplit error: Entry too big to split (mnt/drived/dave/Installed/spybotsd12.exe)


--However, the ' split ' program itself has no such limitation. I split the Knoppix DVD Beta ISO into CDR700-sized chunks, and got them back together with the ' cat ' program, and the result even passed the md5sum test.

--Thus:


' split -b 1m rizzledizzle.zip rizdiz '

--To get around this limitation in the future, consider investing in one or more of the following:

o 100Mbit Ethernet cards (can be had for ~$5 these days)

o USB Ethernet cable (Farallon)

o USB or Parallel port Zip drive (Get the 100Meg if you can find it, and ' modprobe ppa ')

--If you get Ethernet going, you can have Fun with Netcat(TM). 8)
