批处理脚本显示文本文件中的 n 到 m 行并保存新的文本文件

Question

I have found code (see below) but I do not have the ability to encode. I want to select the desired part (lines) from text file and save in another text file! Thank you for all your help!

CODE:

@echo OFF
:: Get the number of lines in the file
set LINES=0
for /f "delims==" %%I in (data.txt) do (
set /a LINES=LINES+1
)

:: Print the last 10 lines
set /a LINES=LINES-10
more +%LINES% < data.txt

Answer 1

Note The following reflects your question body and code content only ignoring your question title text.

Here's a script which will do what your question code does except it outputs to a file.

The output file will be written to the current directory and be named, Name -Last X.ext . Where Name and .ext will match the same name and extension as your source file and X will be the number of lines of output.

The only changes you would ever need to make would be to the source file on line 3 and the last number of lines to output on line 4.

@Echo Off

Set "SrcFile=data.txt"
Set "LastNum=10"

Rem If SrcFile doesn't exist or LastNum isn't at least 1 exit the script
If Not Exist "%SrcFile%" Exit/B
If 1%LastNum% Lss 11 Exit/B

Rem Calculate line number for first line of output
Set "#=-%LastNum%"
For /F "Delims=" %%A In ('Find /V /C ""^<"%SrcFile%"') Do Set/A #+=%%A

Rem Re-calculation for files with less lines than LastNum
If %#% Lss 0 Set/A "LastNum+=#, #=0"

Rem Create destination filename for output
For %%A In ("%SrcFile%") Do Set "$=%%~nA-Last%LastNum%%%~xA"

Rem Output to destination file
More +%#% "%SrcFile%">"%$%"

Note that More will change tab s to a sequence of space s
