Hi all, My requirement is that i have a file eg : abc.txt, then I need to search the string 'black box'. let's say that i found 6 occurences of the string black box in my file abc.txt, now after this string black box, I have some text of type: 1, 2323, 9849438, 539039 2, 4394983, 494938, 4954095 3, 5o343049, 4934, 999349838 ... and so on. here I need to take out all the lines after string black box, which is not fixed there may be 10 or 20 lines. one more thing to note is that I have to only take out those after black box which have the value in next line always incremented by 1. ie, if the sample file is of type : black box 1, 3232, 32323, 32323, 54854 2, iuriu, 238372, 68685, 96589 3, uuery, 585, 459584, 59 kklsfjsjisiof fsifsfsjsjklfsklfj skfkljsf black box 4, iuwieuo, wour, 3943434 5, oiieq, 4874, 945848 oritr]iprit]r trotirtrtoorotirit trtrtioirt]irtiurtrr black box 6, iidsdjks, 88343, 95696586 7, iieuiure, 3847, 3943948 8, 73, itr, 849584, kkjfg 9, eirieu,iiuru, woeooiwe
So I don't have to take 'kklsfjsjisiof' after '3, uuery, 585, 459584, 59 also there is no fixed no of lines to expect after black box., it could vary. the only input the user would be providing is the filename and nothing else. so far I have been able to find all the occurences of string blackbox but am stuck after that.

What do you mean by 'take out' those lines? Do you want to print them on console or write them to a file? Anyway, put down your code here, we can try to repair it.
