You’ll need to modify this based on your needs, but the script below will loop through the file ‘directories.txt’, and ECHO the contents of the line until you hit the maximum number of lines set in maxlines.

@ECHO OFF
setlocal enabledelayedexpansion

SET /A maxlines=1
SET /A linecount=0

FOR /F %%A IN (directories.txt) DO ( 
  IF !linecount! GEQ %maxlines% GOTO ExitLoop
  ECHO %%A 
  SET /A linecount+=1
)

:ExitLoop
