Why does Scala sbt update every time I start it from command prompt?

I hope this helps you . I had a struggle to make this:
It displays the date on the right side when the command has been executed. It does not overwrite the command shown. Warning: it may overwrite the current RPROMPT.

strlen () {
    FOO=$1
    local zero='%([BSUbfksu]|([FB]|){*})'
    LEN=${#${(S%%)FOO//$~zero/}}
    echo $LEN
}

# show right prompt with date ONLY when command is executed
preexec () {
    DATE=$( date +"[%H:%M:%S]" )
    local len_right=$( strlen "$DATE" )
    len_right=$(( $len_right+1 ))
    local right_start=$(($COLUMNS - $len_right))

    local len_cmd=$( strlen "$@" )
    local len_prompt=$(strlen "$PROMPT" )
    local len_left=$(($len_cmd+$len_prompt))

    RDATE="\033[${right_start}C ${DATE}"

    if [ $len_left -lt $right_start ]; then
        # command does not overwrite right prompt
        # ok to move up one line
        echo -e "\033[1A${RDATE}"
    else
        echo -e "${RDATE}"
    fi

}

this one helps. Right click on solution (in solution explorer view) -> properties -> Debug -> Command line arguments.

I wish this helpful for you It seems that you need loop, loop does something while condition is true.

var nick = prompt("Please enter your name", "");
while (nick == "" || nick == null) {
  nick = prompt("Please enter your name", "");
}
$.connection.chathub.server.sendnick(nick);

will help you It is very likely that you are trying to do the actual work in the OnStart() call instead of off-loading it to another thread. The OnStart() is used to initialize the service, but it has to return in order for the Service Manager to update the service state at a minimum.
To do this correctly, the main loop of your service where the work is done should be put in a foreground thread that is started in the OnStart() callback, which allows the OnStart() call to return in a timely fashion. That should prevent the error you're seeing.

help you fix your problem I am getting this error when trying exec one command in PowerShell: ,
Can someone please help me figure out why this is happening?
