How to compress a RAR file into multiple parts
This is very useful when a big file is wanted to be separated into multiple smaller, compressed files. For that, all you should do is to type in the terminal:
$ sudo apt-get install rar
$ rar a -m5 -v5M -R <name> <file_to_compress>
The options mean:
rar- we are going to use Rar program.a- adding files.-m5- compression level (0-store (fast)...3-default...5-maximum(slow)).v5M- size of the parts: 5 Megabytes (-v5M), 3 Gigabytes (-v3G) and so on.<name>- name of the archive you are creating.<file_to_compress>- files or folder you wish to add to the archive.
