How does batch process find the first data string in a row

This article mainly introduces the batch processing how to find the first data string in the row, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take you to know it.

The code is as follows:

@ echo off

:: find a record that looks like

The first number string of::

:: it is obtained by detecting the type of each character, but it is very inefficient

Set num=0

Setlocal enabledelayedexpansion

For / f "delims="% I in (input.txt) do call: intercept "% I"

Echo value=%str_%

Pause

Goto: eof

: intercept

Set str=%1

Set str=%str:~2,-2%

If not "% str%" = "" echo. "% str:~0,1%" | findstr "[0-9]" > nul & (

Set num=1&set stranded rooms stranded strings% stranded flowers 0Mague 1% conversation calls: intercept "! str:~1!") | | (

If% num% equ 0 call: intercept "! str:~1!"

)

Goto: eof

Helpless scheme, which does not rely on the relationship between characters, will get any value after value=, and the speed is very fast.

String of

@ echo off

Setlocal enabledelayedexpansion

FOR / f "delims="% I in (input.txt) do (

Set "tasking%% I"

Set "tweezers"

Set "tweets" =! "

Set "tasking roomt: | =!"

Call: sub! t!

)

Pause

Goto: eof

: sub

If "% 1" = "" exit / b

If "% F%" = "1" echo 1 & set Fidel0

If "% 1" = = "value" set Fair1

Shift

Goto sub
