Is there a way scroll text instead of page?

Sleeping for less than a second is not a real good idea in a script. The overhead required to launch a process is too great. The right thing would be to switch to c. But it is easy to write a program like sleep that will sleep for less than a second if you want to give it a try. I wrote one that I call "nodoff". It sleeps for milliseconds. So "nodoff 500" is a half a second. Here it is...

Code:

#ifdef __STDC__
#define PROTOTYPICAL
#endif
#ifdef __cplusplus
#define PROTOTYPICAL
#endif

#include <stdlib.h>
#include <sys/time.h>

#ifdef PROTOTYPICAL
int main(int argc, char *argv[])
#else
main(argc,argv)
char *argv[];
#endif

{
        int millisecs, microsecs;
        struct timeval tv;

        millisecs=atoi(argv[1]);
        microsecs=millisecs*1000;

        tv.tv_sec=microsecs/1000000;
        tv.tv_usec=microsecs%1000000;

        select(0, NULL, NULL, NULL, &tv);
        exit(0);
}
