In your if test you check the number of parameters and check to see if there is exactly one then throw the message. It should be zero rather than one because it doesn't count the current process name. On that note I might suggest replacing 'elev' in the Usage text with $0 so it can reflect the file it was called as. On and while quoting works there are better ways as Eric had already suggested. I didn't bother changing it but the following script works well and is tested. #!/bin/bash if [ $# -eq 0 ] then echo Usage: $0 program arg1 arg2 ... exit 1 fi prog=$1 shift exec cygstart --action=runas `which $prog` $@ On that note if you plan on reusing the script on xp or older (for portability) then you might want to check the platform os so that you don't use that action setting on them. The runas action is only valid on Windows Vista and Windows 7 since that is when it was added.

scripting elevated privilege on Windows 7
I am dealing with Windows UAC for the first time. From a script, I would like to launch a process with elevated (administrative) privilege. I can accept that Windows will pop up a modal dialog box confirming the elevated privilege. Is there an existing utility in Cygwin or elsewhere. An example of what I would like: I have a program named backall that I want to execute with administrative privelege. I am looking for some command xxx that I could invoke from a shell script as xxx backall Does such a utility exist? If I wanted to enhance cygstart to support this feature, which Microsoft API should I use? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

If I wanted to enhance cygstart to support this feature, which Microsoft API should I use? I took a look at the source code as well as did some research and luckily ShellExecuteEx already has a provision for this. Cygstart also has a parameter that will allow for this although there is no quick option for it. I have tested and verified. It will not path search so you must specify the file location or be in the folder where the program resides. Run the following command and it will prompt for elevation. cygstart --action=runas command Replace command with the actual command. This is an example and it does prompt and elevate. cygstart --action=runas /cygdrive/c/windows/system32/cmd.exe Robert Pendell shi...@elite-systems.org CAcert Assurer A perfect world is one of chaos. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
