Batch 脚本中使用 IF EXIST 语句时，总是提示
The syntax of the command is incorrect.
原始 bat 脚本如下：
ECHO OFF SET project="C:\Temp" IF EXIST %project%\build.log( ECHO File found )ELSE( ECHO File missing )
原因是遗漏了起关键作用的 空格。
ECHO OFF SET project="C:\Temp"
REM There must be a space placed before the parenthesis(IF EXIST %project%\build.log ( ECHO File found ) ELSE ( ECHO File missing )
REM 圆括号 ( 前要留有一个空格。
