The other command could just be
printf '' >> fileto not overwrite it. Or even simpler>>fileand then interruptor
:>>filethen you don't need to interrupt.“:>>” is “append null” right? Do you get a file with a single ASCII NUL or is it truly empty?
Not really. I believe : is the "true" builtin. So it's like running a program that exits with zero and writes nothing to stdout. The >> streams the empty stdout into the named file.
