E:\>str.bat 111.txt
显示:
str1=ncrlog\15600\20070111.txt:COM
str2=MOBILE:13705553216
环境变量 str3 没有定义

"for /f "tokens=1,2,3 delims==, " %%i in (%1) do"
for命令扫描111.txt的1行,赋值一次%%i, %%j, %%k,

结果正好与111new.txt显示顺序对应.

探讨:
for命令
扫描111.txt中的第1行时,test.bat中C部分符合条件,执行C,到END再返回START;
扫描111.txt中的第2行时,test.bat中D部分符合条件,执行D,到END再返回START;
扫描111.txt中的第3行时,test.bat中B部分符合条件,执行B,到END再返回START;
扫描111.txt中的第4行时,test.bat中A部分符合条件,执行A,到END再返回START.

for命令是一行一行地扫描文本文件,for命令体(START到END之间)中的语句是按顺序执行.

增加对ACCEPTED的判断!

test2.bat

@echo off

set str1=%%i

if !flag! equ 2 (
if "!str3:~-8!"=="ACCEPTED" (
echo !name! !TYPE! !CUSTOM_NO! !CARD! !AMOUNT!
)
set flag=
)
if !flag! equ 1 (

set CARD=!str3!
set flag=2
)

rem MOBILE
if "!str2:~0,6!"=="MOBILE" (
set TYPE=!str1:~-3,3! MOBILE
set CUSTOM_NO=!str2:~-11!
if "!TYPE:~0,3!"=="UNI" set CUSTOM_NO=!str3!

DATE TYPE CUSTOM_NO CARD AMOUNT
20070104 UNI MOBILE 13305555353 6228790915000010566 100.00

如果用test.bat执行
test.bat

@echo off
setlocal enabledelayedexpansion
echo DATE TYPE CUSTOM_NO CARD AMOUNT
for /f "tokens=1,2,3 delims==, " %%i in (%1) do (
if !flag! equ 2 (
echo !name! !TYPE! !CUSTOM_NO! !CARD! !AMOUNT!
set flag=
)
if !flag! equ 1 (
set CARD=%%k
set flag=2
)
set str=%%i
set var=%%j
rem MOBILE
if "!var:~0,6!"=="MOBILE" (
set TYPE=!str:~-3,3! MOBILE
set CUSTOM_NO=!var:~-11!
if "!TYPE:~0,3!"=="UNI" set CUSTOM_NO=%%k
)
rem TELEPHONE
if "!str:~-17,9!"=="TELEPHONE" (
set TYPE=TELEPHONE
set CUSTOM_NO=!str:~-7!
)
rem WATER
if "!str:~-14,5!"=="WATER" (
set TYPE=WATER
set CUSTOM_NO=!str:~-8!
)
rem ELEC
if "!str:~-5,4!"=="ELEC" (
set TYPE=ELEC
set CUSTOM_NO=!var:~-8!
)
rem GAS
if "!str:~-4,3!"=="GAS" (
set TYPE=GAS
set CUSTOM_NO=!var:~-10!
)

if "!var:~-2,1!"=="." (
set name=%%~ni
set AMOUNT=%%j
set flag=1
)
if "!var:~-3,1!"=="." (
set name=%%~ni
set AMOUNT=%%j
set flag=1
)
)

test.bat 123.txt
结果:

DATE TYPE CUSTOM_NO CARD AMOUNT
20070111 COM MOBILE 13715553216 62232754001719668 100.00
20070109 TELEPHONE 2202834 6228790915000112760 73.00
20070104 UNI MOBILE 13305555353 6228790915000010566 100.00

如果,不做ACCEPTED条件的判断,没有ACCEPTED的将不显示!!!
特别地交易2(TELEPHONE)与交易3(WATER)的结果就不同!
而且如果将2,3位置颠倒,显示的结果就会不同!!!

这样写不是更好理解吗!!!


@echo off
setlocal enabledelayedexpansion
echo DATE CARD AMOUNT
for /f "tokens=1,2* delims== " %%i in (test.txt) do (
set var=%%j
if "!var:~-3,1!"=="." (
set name=%%~ni
set AMOUNT=%%j
set flag=1
)

if !flag! equ 1 (
set CARD=%%k
set CARD=!CARD:~0,19!
set flag=2
)

if !flag! equ 2 (
echo !name! !CARD! !AMOUNT!
set flag=
)

)
pause

19楼,讲得对"上面的写法理解是不大好",不过只是简单地改变上下顺序是不行的!需要修改内容!
而且是"namejm"斑竹帮忙想出来,我就只好尊重他的写法了!

test.txt
ncrlog\15600\20070111.txt:COM MOBILE:13705553216
ncrlog\15600\20070111.txt:AMOUNT=100.00
ncrlog\15600\20070111.txt: MTR 62232754000719668
ncrlog\15600\20070111.txt: 15:04 MTR ACCEPTED

执行你的bat,得到的是:
DATE CARD AMOUNT
20070111 100.00

for扫描test.txt,第1行不满足,pass!

只有test.txt第2行中,
ncrlog\15600\20070111.txt:AMOUNT=100.00
满足for命令中条件,
if "!var:~-3,1!"=="." (
set name=%%~ni
set AMOUNT=%%j
set flag=1
)
for命令顺序执行下面的行,显示出来,
但是,for继续扫描第3,4行,不满足条件,所以,不能取到!CARD!的值!

修改19楼的bat文件
test.bat

@echo off
setlocal enabledelayedexpansion
echo DATE CUSTOM_NO CARD AMOUNT
for /f "tokens=1,2* delims== " %%i in (%1) do (
set sub=%%i
set var=%%j

if "!sub:~-3,3!"=="COM" (
set TYPE=COM
set CUSTOM_NO=!var:~7!
)

if "!var:~-3,1!"=="." (
set name=%%~ni
set AMOUNT=%%j
)

if "%%j"=="MTR" (
set CARD=%%k
set CARD=!CARD:~0,19!
set flag=1
)

if "%%k"=="MTR ACCEPTED" (
set flag=2
)

if !flag! equ 2 (
echo !name! !CUSTOM_NO! !CARD! !AMOUNT!
set flag=
)

)
pause

执行
test.bat test.txt
得到:
DATE CUSTOM_NO CARD AMOUNT
20070111 13705553216 62232754000719668 100.00
请按任意键继续. . .
