In bash you can cast a command named
clear to clear all the screen commands.
echo you can print whatever you want onscreen..
In my simple scripts I often have the need of print a percentage of what's being done with my commands..
So I could do something like..
echo "89%" echo "90%" echo "91%"
and so on..
what I hate is getting the screen full of percent updates...
89% 90% 91% ...
what I would like is to learn if there's a special character combination (eg. "\033[01;31m") that could be echoed with bash or php echo and tells the console "remove the last previous printed character.."
doing so by using something like: (php example)
echo str_repeat($neg_character, strlen($last_percentage_update_string)); echo $new_percentage_update_string;
I would get the new string printed at the exact position of the previous one without have the screen full of lines
Otherwise I look for an approach to do the same in other ways always using bash and php scripts (please include actual working examples at least with a debian9 console and php7)
