#set -- "$@"
#. /dev/null
if : || [[ "$1" != "set "* ]] ; then
#echo '$ '
#echo "$1" ; eval "$1"
echo '$ ' >&2
#echo "$1" >&2 ; eval "$1"

Wait until specified time has been reached. Time format is exactly the same as the format accepted by "date -d time". (bash shell) (see example in comment) Usage: $ . wait_until.sh time
##set -- "$(( `date -d "$1" +%s`-`date +%s` ))"
#set -- "$(( `date -d "$1" +%s`-`date +%s` ))" "$2"
#[[ "$2" == "" ]] || set -- "$(( $1+$2*60 ))"
##echo "$1"
#set -- "$(( $1>=0 ? $1 : 0 ))"
#. /dev/null
##echo "$1"
#sleep -- "$1"
# * the above not work after suspend or hibernate
