Windows批处理文件-从当前日期计算文件名

这类似于一个查找表:

set month_01=JAN
set month_02=FEB
set month_03=MAR
@rem ...

set number=02

for %%a in (month_%number%) do call set month_as_text=%%%%a%%

echo %month_as_text%

%number% for 循环用于取消对匹配变量名的引用。

甚至更短:

set number=02

for /f "tokens=%number%" %%m in ("JAN FEB MAR APR ...") do set month_as_text=%m

echo %month_as_text%

编辑:

Johannes建议对第1版进行速记:

set month_01=JAN
set month_02=FEB
set month_03=MAR
@rem ...

set number=02

setlocal enabledelayedexpansion

set month_as_text=!month_%number%!    

echo %month_as_text%

你总是可以手工翻译数字到文本,比如:

if %MM%==01 set MM=Jan
if %MM%==02 set MM=Feb
if %MM%==03 set MM=Mar
if %MM%==04 set MM=Apr
etc.

for /f "tokens=08" %a in ("A B C D E F G H I J") do echo %a

如果你更换 08 上面有 09 它也会失败。如果你使用 07 10

months=JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
:: get the month as a 2-digit number
set number=%date:~4,2%
:: remove leading zero
for /f "tokens=* delims=0" %%a in ("%number%") do set number=%%a
:: index into array to get month name
for /f "tokens=%number%" %%m in ("%months%") do set month_as_text=%%m
:: print month name
echo %month_as_text%
