Use -n +1
to make tail read the file from the start:
tail -n +1 -f /var/log/messages | grep sync_complete

I have BusyBox v1.21.0 installed and it has got very basic grep operation, no --line-buffered option
grep sync_complete /var/log/messages
tail -f /var/log/messages | grep sync_complete
is it possible to combine above commands into single line command? thanks!
