/ f循环的批处理脚本不显示所有标记

Question

我有weather.txt

January,Snowy,02
February,Rainy,15
March,Sunny,25

和main.cmd

@echo off
for /f "tokens=1,3 delims=," %%M in (weather.txt) do (echo %%M %%T)

我期待输出

January 02
February 15
March 25

但是我得到了

January %T
February %T
March %T

帮助THX

Answer 1

如果您在%%T中执行了for，则使用%%M很奇怪。

cmd不能假定变量，它们必须按顺序排列。所以对于代币1和3，如果你从%% M开始，你需要下一个按字母顺序排列的字母才能显示该代币，而不仅仅是一个随机字母。因此，您的代码应该是：

@echo off
for /f "tokens=1,3 delims=," %%M in (weather.txt) do (echo %%M %%N)
