I have a file which contains so many lines and variable number of lines are treated as a record. For example *first ooooo xxxxx ttttt mmmm vvvvvvv *end uuu bbbb *first kkkkvvvvvv nnnn mmmmm kkkkk fffff gggg ffff kkkk lllll *end. Here the lines from *first to *end are treated as a record. The number of lines between *first and *end is not same for all the records. Suppose there are 100 records (or number of records are not predefined)like the format given in the above example. Now the entire file needs to split into two files, first having 40 and remaining in the second file. Can we split using sort utility? If possible then what is the sort card?
