Android源代码同步脚本（增加设置线程参数）

#!/bin/sh
#Filename: repo_sync.sh
count=
ret=
while [ $ret -ne  ]
do
#输入参数1,用作同步的线程数
#如果什么参数都不输入，默认线程为4
#usage: ./repo_sync.sh
if [ $ -lt  ] && [ $ -gt  ]; then
        echo "start repo thread is " $
        repo sync -j$
else
        echo "use default repo thread 4"
        repo sync -j4
fi

ret=$?
count=$(( $count + ))
echo "try $count, ret: $ret"
done
echo "try $count, ret: $ret"
