从显示文本文件行批处理文件 [英] Displaying lines from text file in a batch file

问题描述

喜
我试着找到一个脚本，可以让我显示行号＃行号和＃以及＃线 - ＃从一个批处理文件的文本文件？我在这里找到这个脚本在这个网站。

Hi I'm tryin' to find a script that will let me display "linenumber# and linenumber# as well as lines#-#" from a text file in a batch file? I found this script here on this site..

@echo off
setlocal enabledelayedexpansion
if [%1] == [] goto usage
if [%2] == [] goto usage

SET /a counter=0

for /f "usebackq delims=" %%a in (%2) do (
if "!counter!"=="%1" goto exit
echo %%a
set /a counter+=1
)

goto exit

:usage
echo Usage: head.bat COUNT FILENAME

:exit

和它的伟大工程:)但它抓住的行数从文本文件的顶部。我想能够显示在文本文件中的某些线，以及一个范围，如果可能..

And it works great :) But it grabs the number of lines from the top of the text file. I want to be able to display certain lines in the text file, as well as a range if possible..

EG：我有30行的文本文件，我想显示1-4行; 7-11; 13; 17-20; 22; 26安培; 29

EG: I have a text file with 30 lines, and I want to display lines 1-4; 7-11; 13; 17-20; 22; 26 & 29

推荐答案

下面是上面的示例批处理文件的一个简单的修改。复制code以下为文件并将其命名为LineDisplay.bat - 它采用FirstLineNumber和LastLineNumber作为参数。例如：LineDisplay test.txt的12月30日（读线12-30）

Here's a simple modification of the sample batch file above. Copy the code below to file and name it "LineDisplay.bat" - it takes the FirstLineNumber and LastLineNumber as parameters. Example: LineDisplay test.txt 12 30 (to read lines 12-30)

@echo off
setlocal enabledelayedexpansion
if [%1] == [] goto usage
if [%2] == [] goto usage
if [%3] == [] goto usage

set /a FirstLineNumber = %2
set /a LastLineNumber = %3

echo Reading from Line !FirstLineNumber! to !LastLineNumber!


SET /a counter=1

for /f "usebackq delims=" %%a in (%1) do (
    if !counter! GTR !LastLineNumber! goto exit
    if !counter! GEQ !FirstLineNumber! echo !counter! %%a
    set /a counter+=1
)

goto exit

:usage
echo Usage: LineDisplay.bat FILENAME FirstLineNumber LastLineNumber

:exit
