An application I am developing locally logs it's output to files formatted with the current timestamp such as
To make it simple to be able to tail the current's day log in a terminal window, I have a symlink named
current.log which points to today's log.
At the start of work each day, I need to kill the tail process, point the symlink at today's file, and then re-run the command to
tail -f current.log.
Is it possible to change the target of the symlink without having to restart
tail - by changing the target of the file handle without
tail being any wiser?
To automate this "start of new work day" task it would be easy to setup a cron'ed script to point the symlink at today's file, but it seems that the existing
tail process would have no idea that the target has changed.
