Data manipulation, Please help..

Hello,

I have a huge set of data that needs to be reformatted.
Here is a simple example to explain the process.
I have number n=5 and a input with many numbers separated with comma:

Code:
0.49876577,-0.03160753,0.60992502,0.00361167,0.01401017,0.54274066,-0.04881392,-0.01454749,0.02569629,0.04952051,-0.01458124,-0.14468019,0.13155655,0.01912278,0.15125587

after the process, the output looks like:
Code:
   1          0.49876577
   2         -0.03160753          0.60992502
   3          0.00361167          0.01401017          0.54274066
   4         -0.04881392         -0.01454749          0.02569629          0.04952051
   5         -0.01458124         -0.14468019          0.13155655          0.01912278
   5          0.15125587

That starts from 1 and end with 5 (max n) with maximum 4 numbers in one line. So, if the n >4, that means we need more lines to print all numbers relating to n. Here, 5 is 4+1; if n goes up to 9, that will be three lines with 4+ 4+1. all these three lines begin with number n and followed by the numbers from the input.

If n is small, we could do it simply by hand. However, if n goes up to 100, it's a nightmare to manipulate.

Thanks so much for your kind help!

Here is a link for an input with n=45 and the corresponding output

Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
