Shell Programming and Scripting

Hi there,

I produced a script that can sometimes take a lot of time to run. To make sure that it was running I was printing ". " to the screen. I found this could easliy scroll through lots of pages before it finsihed. So I came up with this.

I put this at the beginnig.

Code:

do_next()
{
        echo "\b\b\b${next[${next_count}]}\c"
        let next_count=$next_count+1
        if [ $next_count -gt 3 ]
        then
        {
                next_count=0
        }
        fi
}

initialise()
{
        next[0]="[\\]"
        next[1]="[|]"
        next[2]="[/]"
        next[3]="[-]"
        next_count=0
}


initialise

Then after a point in your script were your taking an action you can invoke do_next. I do it after a succesful rm file, just to show it is removing files.

Enjoy.
