Windows - How to count no of lines in text file and store the value into a variable using batch script?

You can use the following batch script to count the number of lines in a text file and store the value in a variable:

@echo off setlocal enabledelayedexpansion set "filePath=your_text_file.txt" set "lineCount=0" REM Loop through each line in the file for /f "delims=" %%i in ('type "%filePath%" ^| find /c /v ""') do ( set /a lineCount=%%i ) echo Number of lines in %filePath%: %lineCount% endlocal

Replace your_text_file.txt with the actual name of your text file. This script uses a for /f loop to process each line in the file and increments the lineCount variable. Finally, it prints the number of lines to the console.

Save this script in a .bat file and run it in the same directory as your text file.

Examples

  1. "Batch script to count lines in a text file and store in a variable"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "count=0" for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a" echo Number of lines: %count%

    Description: Uses a for /f loop with type and find to count lines in a text file and stores the count in a variable.

  2. "Batch script to count lines in multiple text files and sum the total"

    @echo off setlocal enabledelayedexpansion set "total=0" for %%f in (file1.txt file2.txt file3.txt) do ( set "count=0" for /f %%a in ('type "%%f" ^| find /c /v ""') do set "count=%%a" set /a total+=count ) echo Total lines: %total%

    Description: Counts lines in multiple text files and calculates the total lines, storing it in the total variable.

  3. "Batch script to count lines excluding empty lines in a text file"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "count=0" for /f %%a in ('find /c /v "" "%file%"') do set "count=%%a" echo Number of non-empty lines: %count%

    Description: Uses find /c /v "" to exclude empty lines and count only non-empty lines in a text file.

  4. "Batch file to count lines in a text file with specific string match"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "string=keyword" set "count=0" for /f %%a in ('find /c "%string%" "%file%"') do set "count=%%a" echo Number of lines with "%string%": %count%

    Description: Counts lines in a text file that contain a specific keyword (string match) and stores the count in a variable.

  5. "Batch script to count lines and output results to a text file"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "count=0" for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a" echo Number of lines: %count% > result.txt

    Description: Counts lines in a text file and outputs the results, including the count, to a separate text file.

  6. "Batch script to count lines in a remote text file over a network"

    @echo off setlocal enabledelayedexpansion set "file=\\servername\share\myfile.txt" set "count=0" for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a" echo Number of lines: %count%

    Description: Counts lines in a text file located on a remote server over a network.

  7. "Batch file to count lines and handle large text files efficiently"

    @echo off setlocal enabledelayedexpansion set "file=mylargefile.txt" set "count=0" for /f %%a in ('find /c /v "" "%file%"') do set "count=%%a" echo Number of lines: %count%

    Description: Uses find /c /v "" for efficient counting of lines, suitable for large text files.

  8. "Batch script to count lines in a text file with a specific encoding"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "encoding=UTF-8" set "count=0" for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a" echo Number of lines (using %encoding% encoding): %count%

    Description: Counts lines in a text file with a specified encoding, in this case, UTF-8.

  9. "Batch file to count lines and show progress during execution"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "count=0" for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a" && echo !count! lines processed echo Number of lines: %count%

    Description: Displays progress during the execution of the batch script, showing the number of lines processed.

  10. "Batch script to count lines in a text file and handle errors"

    @echo off setlocal enabledelayedexpansion set "file=myfile.txt" set "count=0" (for /f %%a in ('type "%file%" ^| find /c /v ""') do set "count=%%a") || set "count=Error" echo Number of lines: %count%

    Description: Handles potential errors during counting and sets the count to "Error" in case of issues.
