Jump scroll in PuTTY?

by

I have a file contains many lines, like 1 million lines, and cat the_file takes too much time to scroll.

$ time cat 1m
......
cat 1m  0.00s user 11.21s system 28% cpu 38.839 total

How to make it faster? Like xterm or urxvt’s jumpScroll option?

I’m using PuTTY 0.62 and Windows 8 CP, If Windows 7 is necessary, I can change.

Here is the code I used to generate the file:

#include <stdio.h>

int
main(void) {
        int i;
        for (i = 2; i < 999999; i++) {
                printf("%d\n", i);
        }
        return 0;
}

Answer

You can’t. This is why we shouldn’t log to stdout from our inner loops.

Meaningful logging can be implemented with modulus operations, but I get from your comments that you are asking if you can speed up putty.

Printing to stdout is viewing the file, in essence. Writing ‘blind’ to a file will be much faster, but this time lag you experience is pretty constant.
