Display * * etc while processing data thru AWK 1

[jgl99]

How do I display * * * etc (loop) while awk is processing a large data file?

I assume you mean that you want to print out a progress bar of one * for every n lines. Something like this would work but only if you are not using standard out for your normal pocessing. Otherwise, you would have to figure out how to write to stderr or directly to the screen, which I don't know how to do.

  if (NR % 1 == 0) {
    printf("*");
    if (++knt == 80) {
      print
      knt = 0;
    }
  }

Hope this helps. CaKiwi

Sorry, that should have been
[tt]
if (NR % 1 == 0) {
printf("*"
if (++knt == 80) {
print ""
knt = 0;
}
}
[/tt] CaKiwi

Ok it's a little late in the day for me. How about this to print one * for every 100 lines.
[tt]
if (NR % 100 == 0) {
printf("*"
if (++knt == 80) {
print ""
knt = 0;
}
} CaKiwi

Hi,

You can write to stderr with the syntax :

printf "*" | "cat 2>&1"

If you use gawk :

printf "*" > "/dev/stderr" Jean Pierre.

Thanks aigles, that will come in handy someday. CaKiwi
