how to search for and strip a blank line from text file

[Guest]

In batch file, how do I search for and strip blank line from a text file?

for /f %q in (file.txt) do (if {%q} NEQ {} echo %q>>file2.txt)

That'll give you a new file sans blank lines, which you can then rename to
the original file name after deleting the original file.
