Hi, I need to create a program which reads a file from the LAN, and that file is continuously updated (kind of log). The file increases continuously, and it can become very big.
On every read, I need to read just the lines for the current day (which is specified in each line) and jump over the lines from the previous days. The problem is that if I just open() the file and verify each line to see if it is a good one, takes very much time, and I need to find a faster solution. Checking each line might take a long time, but I think that verifying each line means downloading the whole content of the file on my computer, and this will also make the program lose much time. Do you have any idea what can I do to make the program run faster? I am thinking to make the program in such a way that after the first run, it gets the line number of the first line from the current day, or the number of the first bit of the start of that line, then on next times it runs, it jumps directly to that line somehow (?), or directly to that bit (using seek), but I don't know if in that case the content of the file won't be also downloaded to my computer. Do you have any idea how I can download just a part of a file from the network? Help! Thank you.
