I used split -b 32m "file.bz2" "file.bz2.part-" to split a file and it created more than 50 parts. From googling, the way I found to reassemble the parts is to cat file.bz2.part-aa file.bz2.part-ab > file.bz2, while enumerating all the 50+ parts. Is there an easier way to reassemble the parts wherein I no longer need to list all those parts explicitly?
I'm using Fedora 12.
Today encoders are getting smarter. They can compress Blu ray similar quality in 700MB. It seems header of video file contain info about frame rate, audio/video encoder etc. which can't be guessed. In MPEG audio , every part of file is independently playable. If a movie is binary split into 6 parts & I don't have the first part then it is unplayable.
Code:
example
ls
-rwxrwxrwx 1 root root 280M 2010-12-07 20:23 irn2-cd1.mkv
-rwxrwxrwx 1 root root 50M 2011-05-26 13:09 last-50M-cd2
-rwxrwxrwx 1 root root 50M 2011-05-26 13:44 first-50M-cd1
file *
first-50M-cd1: Matroska data
last-50M-cd2: data
irn2-cd1.mkv: Matroska data
I've a file with a size of 6GB. I would like to compress this file and split them into smaller files. I was also thinking in use bzip2 to compress it, because if offers a good compression rate. How can I split this file into small ones to compress it?

I run a memory-hungry process (mkcromfs) which consumes more memory than I have physical memory on my latop, so it is paging and swappin and thrashing all the time and loadavg is about 2 (compcache is already in use with usual swap partition as well), but slowly moving forward (Although I afraid it will finally try to allocate >2GB and crash draining 2 days of thrashing).
When I want to use the laptop for something else, I stop the process, start X server, firefox and other programs. The problem is that when I start Firefox the loadavg jumps to 10 and the system becomes almost unresponsive at all (long time to turn on/off caps lock, slow mouse cursor position updates, slow switching from X server to Linux console, slow login).
The stopped mkcromfs still holds a lot of memory (464.8 MiB and slowly falling) and moves it to swap only when more memory is needed for some other program, which results in a great slowdown.
How to tell the Linux to swap out this process entirely (e.g. I'm not intending to resume it in short term), possibly waking from swap other data? Also it will be useful to be able to specify the exact swap device to swap the given process out (for example, mkcromfs's memory is useless in ramzswap).
Update: Now I just write a 400-600M of data from /dev/erandom to tmpfs and it makes mkcromfs to shrink. Is there more proper way?
I am attempting to configure my sudoers file, and have quite a few questions.If you can answer any/all of them, I would be grateful.
-Is there a way to set it up so that root gets notified if a user tries to use a command they are not allowed to?
-If something like this already exists on my system, how do I set it up/use it/ read root's messages?
-I see a lecture=always default exists, but can I customize this lecture?
-Is there an easy way to explicitly deny a user sudo permission?
-I see there is an ALL wildcard. Is there something similar to a NONE wildcard?

Anybody know what command I need for this?

I am using rsync to create rotating snapshot style backups of my web files and sending them via SSH to a remote location in order to burn them for offsite storage. This is all working perfect. The remote machine is a Windows Server 2003 which has data that I combine with my web files before burning. I have cygwin installed on the remote server in order to archive and compress the entire backup using tar. (This is not a post about cygwin, I just thought I would mention it in case anyone was wondering how I was running Linux commands after transferring it to the Windows box). After compression, the backup is over 12gb. The next step in my process is to split this tar.gz file into smaller chunks in order to burn them to DVDs. I use dual layer DVDs which are 8.5gb storage size.
I also use cygwin to split the tar.gz into multiple 2gb files using the split command. When I burn them, I only put 3 files on each disk totaling 6gb to leave some padding in case this was a problem. The burn completes and says successful, although it errors out when in verification. I have tried this multiple times and it seems to fail verification at the same point every time which leads me to believe that it has something to do with the data. I have also done tests such as creating smaller backups with completely different data and brning that to a CD-R which worked fine, so I'm convinced this process can work, I just cant get it to work in the right situation. I have also tried burning one of the 7 split files to a dual DVD which also worked fine. I'm wondering if their is a chunk of data that is causing this problem in one of the other split files?
