System Exec VI Calling umount

[rivand]

Hi all,

I need to safe umount my FAT32 filesystem USB mass storage device, and my final customer should be able to do that from the VI Front Panel (running on cRIO-9030 with HMI enabled). I would like to run programmatically a command like:

sudo umount /dev/sdcX

but it is allowed only by admin (not by lvuser). How can I do that?

There is a way to create a bash script calling

su admin

passing directly the password, without prompting it? It seems that

su admin -p 'adminPassword'

doesn't work

Thank you in advance

Andrea

su itself generally requires being run from a terminal (interactive), but of course you can install and configure sudo to work for any user on the system, including lvuser (the user that runs the LVRT runtime)

You need to add your user to sudoers by Visudo command
