我想在批处理文件中的if条件下运行多个命令。
我尝试了下面的代码,但对我不起作用。
IF not exist %directoryPath% (echo Invalid directory. goto :InvalidDirectory) ELSE (echo Sencha app build development started..)
代码:
:EnterDirectory
echo Enter your project directory
set /P directoryPath=
IF exist %directoryPath% (goto :init) ELSE (goto :InvalidDirectory)
:InvalidDirectory
echo This directory does not exists.
(goto :EnterDirectory)
:init
IF not exist %directoryPath% (goto :InvalidDirectory) ELSE (echo Sencha app build development started..)
答案 0 :(得分:2)
在使用批处理文件时,请勿尝试一行完成所有操作。当您对语法的关注不够时(很容易发生),这会使您的脚本不可读,甚至可能会给您带来错误/意外的结果。这种故障很难排除。将其分成多行(理想情况下,每行一个命令):
IF not exist %directoryPath% (
echo Invalid directory.
goto :InvalidDirectory
) ELSE (
echo Sencha app build development started..
)
如果您坚持要一行执行,&
是链接两个命令的正确方法:
IF not exist %directoryPath% (echo Invalid directory. & goto :InvalidDirectory) ELSE (echo Sencha app build development started..)
