Display NotifyOSD Notifcations in Conky?

Question

I want to display the latest NotifyOSD notification in conky, I can display the entire file with

${execi 30 cat ~/.cache/notify-osd.log}

But is it possible to show only the last line of the file? and get it to periodically check the log for changes to the last line?

Answer 1

As you pointed out:

I sorted the problem by using this

${execi 30 cat ~/.cache/notify-osd.log| tail -4}

which works perfectly
