I want to grok how fast a particular file is growing.
I could do
watch ls -l file
And deduce this information from the rate of change.
Is there something similar that would directly output the rate of growth of the file over time?
But beware that it involves acually reading the file, so it might consume a bit more resources than something that watches just file size.
I have a little perl script that I put in my bash environment as a function:
Sleep seconds defaults to 1.
