I. Using RAR
1. Sub-volume compression
Ubuntu does not have the default installation RAR, can be sudo apt-get install RAR, sudo apt-get install unrar to install RAR.
After installation, use the following command for volume compression:
RAR a-vsize Compressed file name or folder
For example: RAR a-v50000k eclipse.rar Eclipse
This command is for the Eclipse folder to be compressed, with a size of 50000k per volume and a compressed file named Eclipse.rar
2. Decompression
Perform on any one of the volumes:
RAR e Eclipse.part1.rar can be.
Second, use tar
1. Sub-volume compression
Tar Cvzpf-eclipse | Split-d-B 50m
The above command is to compress the Eclipse folder into volumes, 50m per volume, and notice that there are spaces in front of eclipse. After compression, it will be named x00,x01,x02 ...
2. Decompression
First you need to merge:
The merged commands are: Cat x*>eclipse.tar.gz
Then unpack: Tar xzvf eclipse.tar.gz
