Weired 'syntax error: unexpected end of file' in bash script
提问by Dilawar
I can't figure out what is wrong with following script.
我无法弄清楚以下脚本有什么问题。
#!/bin/bash
if [ "" = "x" ]
then
echo Pushing web on sharada to origin.
else if [ "" = "y" ]
then
echo Pulling web on sharada from origin.
else
echo "Usage : arg x to push or y to pull."
fi

you are missing closing "fi" at the end.
the else ifconstruct really is not an elifcontinuation, but instead the new iflives within the elseclause of the previous if.
你最后错过了关闭“fi”。该else if构造实际上不是elif延续，而是前一个if的else子句中的新生命if。
so, properly formatted you should have:
所以，正确格式化你应该有：
#!/bin/bash
if [ "" = "x" ]
then
echo Pushing web on sharada to origin.
else
if [ "" = "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"

It should be elif, not else if, as shown below:
应该是elif，不是else if，如下图：
if [ "" = "x" ]
then
echo Pushing web on sharada to origin.
elif [ "" = "y" ]
then
echo Pulling web on sharada from origin.
else
echo "Usage : arg x to push or y to pull."
fi

You have two ifs, therefore you need two fis.
您有两个ifs，因此您需要两个fis。
