How can I install a font from a batch file?

When you install a font all it does is copy the .ttf file to 

%systemroot%\fonts 

and add an entry in 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts. 

This can be automated with a batch file as follows:

install.bat:

xcopy font_name.ttf %systemroot%\fonts

regedit /s font.reg

If you want to install with administrator's rights:

runas /user:domain\userID "xcopy CHL_AVON_CG.ttf %systemroot%\fonts"
regedit /s font.reg

font.reg:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts\]

"CoalhandLuke_Avon_CG (TrueType)"="CHL_AVON_CG.ttf"
