bash 脚本中奇怪的“语法错误：意外的文件结尾”

我无法弄清楚以下脚本有什么问题。

#!/bin/bash 
if [ "$1" = "x" ] 
then
  echo Pushing web on sharada to origin.
else if [ "$1" = "y" ] 
then 
  echo Pulling web on sharada from origin.
else 
  echo "Usage : arg x to push or y to pull."
fi

我在linux（Ubuntu）上xterm.

你错过了最后关闭“fi”。 这else if构造确实不是一个elif延续，但取而代之的是新的if生活在else上一条的条款if.

所以，正确格式化你应该有：

#!/bin/bash 
if [ "$1" = "x" ] 
then
  echo Pushing web on sharada to origin.
else 
  if [ "$1" = "y" ] 
  then 
    echo Pulling web on sharada from origin.
  else 
    echo "Usage : arg x to push or y to pull."
  fi
fi # <-- this closes the first "if"
