How to handle file names with &

[Yanta]

I have a font I want to install called Spirit & Ghost.ttf

The following code processes a list of font files in a folder.

Code: Select all

    SET SRC=%CD:~0,2%
    set SrcPath=%SRC%\PostInstall\%USERNAME%
    
:FONTS
    IF EXIST "%SrcPath%\Fonts\" (
        Echo Installing Custom Fonts
        Echo %time% Installing Custom Fonts >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
        FOR %%a in ("%SrcPath%\Fonts\*.?tf") do call :Installfont "%%~nxa"
        Echo %time% Fonts will not be available until the system has been restarted >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
	)
	Goto SYMLNK

:Installfont
        Set font=%~1
        IF EXIST "%LOCALAPPDATA%\Microsoft\Windows\Fonts\%font%" echo Font %font% already installed. >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
        IF EXIST "%WINDIR%\Fonts\%font%" echo Font %font% already installed. >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
        IF NOT EXIST "%LOCALAPPDATA%\Microsoft\Windows\Fonts\%font%" IF NOT EXIST "%WINDIR%\Fonts\%font%" (
            Set fext=%font:~-3%
            IF /i "%fext%"=="ttf" Set ftype=Truetype
            IF /i "%fext%"=="otf" Set ftype=Opentype
			Echo Installing %font% to "%LOCALAPPDATA%\Microsoft\Windows\Fonts" >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
            Echo Processing font %font% Extension: %fext% Type: "(%ftype%)" >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
			copy "%SrcPath%\Fonts\%font%" "%LOCALAPPDATA%\Microsoft\Windows\Fonts\%font%" /y >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
            REG ADD "HKCU\Software\Microsoft\Windows NT\CurrentVersion\Fonts" /v "%font% (%ftype%)" /d "%LOCALAPPDATA%\Microsoft\Windows\Fonts\%font%" /t REG_SZ /f >>C:\%USERDOMAIN%.PostInstall.Log 2>&1
        )
        exit /b

:SYMLNK 
	Echo Finished

Of course, this fails when it hits the spirit & ghost.ttf file...

Code: Select all

'GHOST.ttf' is not recognized as an internal or external command,
operable program or batch file.

How do I handle file names with & in them?

[OJBakker]

protect set variable from special characters by using double quotes.
change

Code: Select all

set var=value

to

Code: Select all

set "var=value"

protect echo variable from special characters by using double quotes.
change

Code: Select all

echo %var% 

to

Code: Select all

echo "%var%"

The quotes will be visible in the output.
If you don't want visible quotes you will have to escape the special characters in the value of the variable before using echo.
