this tip is taken literally from Superuser but i think it worth spreading..i use it very often in linux which makes command line handling of files enjoyable ;) -not all the time of course- , this little command comes handy when you try transferring huge files on Fat HDDs which support max file size of 4 Gbs...
rar -a -v<size in b,k,m> split.rar files_to_slplit.mkv
in my case ,
rar a -m0 -v1000000k 1.rar *.mkv
