batch script to rename a file with string (with space) from variable

问题

There is a file named doctitle.txt which contains the title. I want to use this title to rename another file, currently name file.pdf, so I did:

for /f "delims=" %%x in (doctitle.txt) do set "DOCTITLE=%%x"
move file.pdf %DOCTITLE%.pdf

This works fine, if there no space in the title string, i.e "DocumentTitle". But fails if there is a space in the title, i.e "Document Title".

What could be done to overcome this issue?

回答1:

Try:

for /f "tokens=*" %%x in (doctitle.txt) do set DOCTITLE=%%~x
move file.pdf "%DOCTITLE%.pdf"

That way, the variable DOCTITLE will not be surrounded with quotes as %%~ removes any quotes.

Quoting for /?:

%~I         - expands %I removing any surrounding quotes (")
