看gif图：

脚本内容如下：

## ------------------------------------------------------------

## usage：$0 "command"
## you must enclosing the command by double-quotes
## example1: $0 "sleep 3;echo haha"
## example2: $0 "service mysql start"

killmyself="pkill -13 -f `basename $0`"

trap "$killmyself" sigint

while true;do
    for i in '-' '\' '|' '/';do
        printf "\r%s" $i
        sleep 0.2
    done
done &

printf "\r%s\n" "`bash -c \"$@\"`"

$killmyself

必须将待运行的命令放进引号中包围，并作为脚本的参数。

## example1: $0 "sleep 3;echo haha"
## example2: $0 "service mysql start"
## example3: $0 "service mysql stop"
