APT style progress bar

prog.sh

#!/bin/bash
# progress bar function
prog() {
    local w=80 p=$1;  shift
    # create a string of spaces, then change them to dots
    printf -v dots "%*s" "$(( $p*$w/100 ))" ""; dots=${dots// /\#};
    # print those dots on a fixed-width space plus the percentage etc.
    printf "\r\e[K|%-*s| %3d %% %s" "$w" "$dots" "$p" "$*";
}
# test loop
for x in {1..100} ; do
    prog "$x" still working...
    sleep .1   # do some work here
done ; echo

I created this to reproduce the false ligatures problem with Berkeley Mono font and apt's progress bar.
