To split and Join file: HJSPLIT or LXSPLIT [ dd or cat as well]

In Ubuntu, I found the lxsplit as easier one to install. HJsplit needs first kylixlib3 libraries to be installed first.

To install hjsplit , the below link would be useful.

For HJSplit:
http://www.treepad.net/download/hjsplitlx.tar.gz
http://www.freebyte.com/linux/libraries/
http://kylixlibs.sourceforge.net/down.html

For lxsplit:
saffrongeek@saffrongeek-laptop:~/Desktop/$wget http://www.freebyte.com/download/lxsplit.tar.gz
saffrongeek@saffrongeek-laptop:~/Desktop/$tar -xvvzf lxsplit.tar.gz
saffrongeek@saffrongeek-laptop:~/Desktop/$ cd lxsplit-0.1.1
saffrongeek@saffrongeek-laptop:~/Desktop/lxsplit-0.1.1$ make
saffrongeek@saffrongeek-laptop:~/Desktop/lxsplit-0.1.1$ sudo make install
cp lxsplit /usr/local/bin

To split use as below:
lxsplit -s  {Namefile.type} 15M
lxsplit -j {Namefile.type.001}

Also, to be independent and available is ‘dd’ and ‘cat’ but all types split of join is not possible.
