This article mainly introduces how to realize the batch processing of reading lines with sensitive characters, 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 a look at it.

The code is as follows:

@ echo off

Ordinary for+findstr statements ignore lines that begin with a semicolon

:: findstr / n. * after using delims=:, all colons at the beginning of the line are ignored

: and!, &,. Special symbols need to be dealt with.

The following code can extract these sensitive characters accurately

:: solved the problem of the maximum recursion layer of setlocal (this problem occurs when setlocal pairs are nested to deal with more than 15 lines of content)

:: can calculate blank lines

:: code by jm 2006-12-12 thanks 3742668 CMD@XP

Set num=0

For / f "delims="% I in ('findstr / n. * test.txt') do (

Set / a num+=1

Set "str=%%i"

Setlocal enabledelayedexpansion

Echo! num! All right:! struts, "rips"!

Endlocal

)

Pause

Goto: eof

@ echo off

:: when more than 15 lines of content, it will bring the problem of the maximum recursion layer of setlocal

:: code by 3742668 2006-12-11 CMD@XP

@ echo off

Setlocal enabledelayedexpansion

Set num=

For / f "eol= delims="% I in ('findstr. * a.txt') do (

Setlocal DISABLEDELAYEDEXPANSION

Set "tmpstr=%%i"

Setlocal enabledelayedexpansion

Set / a num + = 1

Set "! numb trees

)

For / l% I in (1JI% num%) do echo line%% I:!%% I!

Pause

Exit / b 0

@ echo off

Cannot extract the content with exclamation mark correctly

:: code by jm 2006-12-11 CMD@XP

Set num=0

Setlocal enabledelayedexpansion

For / f "delims="% I in ('findstr / n. * test.txt') do (

Set / a num+=1

Set "str=%%i"

Echo! num! All right:! struts, "rips"!

)

Pause

Goto: eof

@ echo off

The result should be enclosed in quotation marks

:: code by jm 2006-12-11 CMD@XP

Set num=0

:: setlocal enabledelayedexpansion

For / f "delims="% I in ('findstr / n. * test.txt') do (

Set / a num+=1

Set "str=%%i"

Call: display

)

Pause

Goto: eof

: display

Line% num% of echo: "% str:*:=%"

Goto: eof

The content of test.txt

: abc

:: xy

;; ef &
