该脚本的源码是为了实现从远程的服务器上面拉文件到本机。

主要是为了实现自动输入密码的功能。

#!/bin/bash
shellPath=$(cd "$(dirname "$0")"; pwd)
pid=0

function check_process_exist(){
	ps_out=`ps -ef | grep taskmanager | grep -v 'grep'`
	result=$(echo $ps_out | grep $1)
    	if [[ "$result" == "" ]]; then
        	return 0
    	else
        	return 1
    	fi
}

/usr/bin/expect <<-EOF
spawn scp $1@$2:$3 "$shellPath/$4"
expect {
"yes/no" { send "yes\r";exp_continue }
"password" { send "$5\r" }
}
expect eof
exit 0
EOF

tar -zxvf $4
python modifyConfig.py $6
cd taskmanager
chmod +x proServer.sh
./proServer.sh start
pid=$(cat pid)
echo "waiting"
while true
do
	check_process_exist $pid
	if [ $? -eq 0 ]; then
        	echo "The process has stoped!"
       		exit 1
    	fi
    	sleep 1
done
