[linux] Split it out

Ever wondered how to transfer a huge file across network without having to worry about disconnection in the middle of the transfer?

How about splitting it into pieces and transfer it piece by piece, that way you won't worry about your connection getting cut off all of a sudden. Then after you have transferred all the pieces, just put it back all together again.

Here's an example

You have a large file about 100mb that needs to be transferred to the other side of the globe

let's split it into 15m each until the size is consumed, by default the prefix of the file is x followed by some letters

to make the file pieces more descriptive let's specify a prefix

we can have numeric suffixes too

to restore the file, we use cat for this job
simple and easy :)

I found a fix to this problem, thanks to chantra of Debuntu

First, download the patch
wget http://www.debuntu.org/sites/www.debuntu.org/files/vmware-7.1-ubuntu10.10-patch-v2.tar_.gz

Extract and run it as root
tar -xzvf vmware-7.1-ubuntu10.10-patch.tar.gz
cd vmware-7.1-ubuntu10.10-patch
sudo ./apply_patch.sh

Then run VMWare again, the modules should compile this time.
