标题: 如何显示位数少于几的数字 [打印本页]
作者: Eblis 时间: 2007-7-3 16:15 标题: 如何显示位数少于几的数字
比如说这段批处理
@echo off
setlocal enabledelayedexpansion
for /f "delims=-" %%a in (20.txt) do (
set a=%%a
if "!a:~5,6!"=="" echo !a!
)
endlocal
%%a都是数字..我想知道123456 654321这样的``我想显示出少于6位的数字..怎么写呢``?setlocal enabledelayedexpansion
for /f "delims=-" %%a in (20.txt) do (
set a=%%a
if "!a:~5,6!"=="" echo !a!
)
endlocal

显示少于6位的数字？
借鉴3742668 荣誉版主 的代码
@echo off
setlocal enabledelayedexpansion
for /f "delims=-" %%a in (a.txt) do (
set str=
for /l %%i in (1 1 6) do (
set str=!str!.
echo %%a|findstr /x !str!
)
)
pause
考虑到效率问题，觉得还是建立一个临时文件比较快。setlocal enabledelayedexpansion
for /f "delims=-" %%a in (a.txt) do (
set str=
for /l %%i in (1 1 6) do (
set str=!str!.
echo %%a|findstr /x !str!
)
)
pause
@echo off
setlocal ENABLEDELAYEDEXPANSION
rem for /f "delims=-" %%a in (20.txt) do echo %%a>>a.txt
for /l %%a in (1 1 3) do (
for /l %%i in (1,1,%%a) do (
set str=!str!.
findstr /x !str! a.txt
)
)
pause>nul

@echo off
setlocal ENABLEDELAYEDEXPANSION
for /f "delims=" %%a in (20.txt) do (
set str=%%a
set str1=!str:~6,1!
if not defined str1 echo %%a
)
pause
setlocal ENABLEDELAYEDEXPANSION
for /f "delims=" %%a in (20.txt) do (
set str=%%a
set str1=!str:~6,1!
if not defined str1 echo %%a
)
pause

这样可以不？
@echo off
setlocal enabledelayedexpansion
for /f "delims=-" %%a in (20.txt) do (
if !a! LSS 10000 echo !a!
set a=
)
endlocal

可以可以 似乎更简单
@echo off
setlocal enabledelayedexpansion
for /f %%a in (20.txt) do (
set a=%%a
if !a! LSS 1000000 echo !a! >>21.txt
)
pause

谢谢了。

@echo off
for /f %%a in (d:\test\123456\123456.txt) do (
if %%a LSS 1000000 echo %%a >>21.txt
