I am trying bleow scripts,but its not showing any result:
Use Test

-- Set Desired file free space in MB after shrink
set @TargetFreeMB = 5000 --need to change the size
-- Set Increment to shrink file by in MB
set @ShrinkIncrementMB = 1000
-- Show Size, Space Used, Unused Space, and Name of all database files
