and so on. I need the sript to read the first line with text and use the #data value to determine how many lines to read below this text line, then read those lines of data, then read the next line with text and use the #data value to count how namy lines to read below that and so on.

To be honext I have no idea where to start from. And honestly I am not completely new to shell scripting but this has challenged me to the core. This is not an assignment, its for my rresearch work am a seniour lecturer in the department of physics at the university of zambia in lusaka, zambia. I hope it is doable.

The read data can be directed to a gnuplot ot output to a file.

Thank you in advance
