Another way might be to use tput cup row column to set the cursor position on the screen, but you have to know what shape screen you have and it's usually better to clear it before you begin so you know that there is nothing to overwrite.

Yet another an alternate could be to just output a dot or other character without the new-line each time round the loop with printf


How much output would you expect, or iterations round your loop? Are you watching a file grow, for instance?

You could:-
Code:
#!/bin/bash

filename=/path/to/bigfile

[ ! -f $filename ] && touch $filename             # Make sure it exists
while true
do
   printf "\r$filename=$(stat -c %s $filename) bytes"
   sleep 1
done

progress_pid=$!

# Do whatever to generate the large file now, e.g. a tar or wget etc.

kill $watcher_pid
echo ; echo "Watcher process ended."

This will show the file growing until your script carries on and terminates the watcher.



Does any of these help? it really depends on what you eventually want to do. If you can put it in context, we might refine our suggestions.



Kind regards,
Robin
