...........No consideration was given to this matter...It's over........... @echo off set runtimes=0 FOR /F "delims=" %%i in (myfile.txt) do ( call :func1 "%%i" "%%i" ) pause pause pause :func1 set /a runtimes=%runtimes%+1 set EL=1 set T1=%1 set T1=%T1: =% if NOT %T1%=="" set EL=0 if %EL%==0 ( if NOT %runtimes%==1 echo+>>done.txt set /p "null=%2"<nul>>done.txt ) goto :EOF

It can be used like this. Note that there is a space before , sed "/^ $/d" # Delete all blank lines in the file sed '/^$/d' # Method 1 sed '/./!d' # Method 2
