我正在尝试运行bash脚本startup_application.sh
该脚本如下：
#!/bin/sh
vncserver
/home/ubuntu/hadoop-2.7.3-3/ctlscript.sh start
每当我尝试运行脚本时，我都会收到以下错误：
sh '/home/ubuntu/startApplication.sh' start
: not foundu/startApplication.sh: 2: /home/ubuntu/startApplication.sh: vncserver
usage: /home/ubuntu/hadoop-2.7.3-3/ctlscript.sh help
