Below I describe how to split a larger file into several small files.
This is useful when the file you want to copy on a stick is bigger than the stick’s capacity.
The file used is this example is a 75 MB .mkv.
I will use lxsplit for splitting and joining the .mkv file. So, I need to install lxsplit:
wget http://sourceforge.net/projects/lxsplit/files/lxsplit/lxsplit-0.2.4.tar.gz/download
Decompression:
ducu@mylaptop:~/temp$ tar -xvvzf lxsplit-0.2.4.tar.gz

-rw-rw-r– ozzie/ozzie 17990 2008-02-02 09:45 lxsplit-0.2.4/COPYING
Access the new folder and give the make command:
cd lxsplit-0.2.4/
make
Next, make install command. This is the result:
ducu@mylaptop:~/temp/lxsplit-0.2.4$ sudo make install
cp lxsplit /usr/local/bin
This is my 75MB .mkv file:
ducu@mylaptop:~/movies/Inside.Man.2006.1080p.HDDVD.x264-SZ/Sample$ ls -alh
total 75M
drwxr-xr-x 2 ducu ducu 4.0K 2009-07-21 21:28 .
drwxr-xr-x 3 ducu ducu 4.0K 2009-06-13 02:15 ..
-rw-r–r– 1 ducu ducu 75M 2009-06-13 02:47 Inside.Man.2006.1080p.HDDVD.x264-SZ-SAMPLE.mkv
I will split the 75 MB file in chunks of 20 MB.
ducu@mylaptop:~/movies/Inside.Man.2006.1080p.HDDVD.x264-SZ/Sample$ lxsplit -s Inside.Man.2006.1080p.HDDVD.x264-SZ-SAMPLE.mkv 20M
Splitting Inside.Man.2006.1080p.HDDVD.x264-SZ-SAMPLE.mkv into 4 pieces.
Inside.Man…SZ-SAMPLE.mkv.001 20971520 bytes
Inside.Man…SZ-SAMPLE.mkv.002 20971520 bytes
Inside.Man…SZ-SAMPLE.mkv.003 20971520 bytes
Inside.Man…SZ-SAMPLE.mkv.004 14767172 bytes
Done!
Now I will join the 4 resulted files:
ducu@mylaptop:~/movies/Inside.Man.2006.1080p.HDDVD.x264-SZ/Sample$ lxsplit -j Inside.Man.2006.1080p.HDDVD.x264-SZ-SAMPLE.mkv.001
Creating merged file `Inside.Man.2006.1080p.HDDVD.x264-SZ-SAMPLE.mkv’.
