Hi, after a small run in with a virus I have decided to enable UAC. The key feature holding me back was the ability to run a program elevated from the command line (unix like "sudo" capability). John Robbins has written a simple "elevate" program (for use with Take Command) that would be extremely useful as an internal function - part of start maybe. I have wrapped up elevate with a simple batch file that starts Take Command commands in a new Take Command shell, and external commands directly, this would also be useful in take command. Start a command as administrator. usage: sudo [/wait|/hide|/pause] <command> - /wait - wait for the elevated program to finish - /hide - hide the elevated command line program - /pause - pause before ending the elevated command line program :start REM Start an elevated command prompt iff %# == 0 then elevate.exe %wait "%ComSpec" return 0 endiff set command=%1 REM Check for a valid program which %@quote[%command] |& egrep -i "is an unknown" >& nul iff %? == 0 then EchoErr %command is an unknwon command. return 1 endiff REM Run an external (not Take Command) program elevated which %@quote[%command] |& egrep -i "is an external" >& nul iff %? == 0 then elevate.exe %wait %$ return 0 endiff REM Run a Take Command program elevated elevate.exe %wait "%ComSpec" /c %hidden %$ %@if[ defined pause ,`&` pause] return 0</command>
