Yes that's safer. stsize is only defined for regular files (or shared mem), so I'll only allow regular files. I'll push a separate patch soon.

what about --ref=- ?

one wants to have a file with the size of a partition plus 5G, e.g. truncate --ref=/dev/sda5 -s +5G myfile This will fail and will be rejected with such a patch. So the user could use: truncate --ref=- -s +5G myfile < /dev/sda5

Just a thought ...

Have a nice day, Berny
