问题描述
我经常需要执行以下命令来压缩文件夹中的所有PNG文件:
I need to execute often the following command which compresses all the PNG files in a folder:
for %i in (*.png) do pngout.exe "%i" /kp
因此，我已将此命令添加到文件png.cmd中，并将该文件夹添加到系统PATH中.
So I have added this command in a file png.cmd and added the folder to the system PATH.
但是，当我从文件系统中的某个点执行命令(png.cmd)时，出现以下错误:
However when I execute the command (png.cmd) from a point in my file system, I get the following error:
C:\Users\Desktop>png
i" /kp was unexpected at this time.
是否有解决此问题的方法，我还在考虑shell将在哪里执行png.cmd命令?在创建png.cmd文件的路径中?我需要在当前的Shell所在的PATH中执行它.
任何想法?非常感谢
Is there a way to fix this problem, also I'm thinking where the shell is going to execute the png.cmd command ? In the path where I've created the png.cmd file ? I'd need to execute it in the current PATH where I'm with the shell.
Any idea?Thanks a alot
推荐答案
当您使用时，您的语法错误是由于在 for 循环变量中仅使用1个％引起的批处理文件，您需要使用2来转义第一个.
Your syntax error is caused by using only 1 % in your for loop variable, when you use a batch file you need to use 2 to escape the first one.
for %%i in (*.png) do pngout.exe "%%i" /kp
关于您的路径问题，请先解决此问题，然后查看是否仍然是问题.
With regards to your path question, fix this first, then see if it's still an issue.
