linux ubuntu bash shell报错 xxx.sh: Syntax error: end of file unexpected (expecting “then“)

代码：run.sh

# creat log dir if it not exists
logDir="./ckpt/"$timeDir
if [ ! -d $logDir  ]; then
  mkdir $logDir
else
  echo $logDir exist
fi

报错：

$ sh run.sh
: not foundrun.sh:
run.sh: 16: run.sh: Syntax error: end of file unexpected (expecting "then")

解决：
需要转换脚本编码方式

$ sudo apt-get install dos2unix
$ dos2unix run.sh
