How do you truncate log files keeping only the latest info ?

I know you can cat /dev/null > log.file to zero it.

Why not copy the current file to a .1 file and zero the original?

I want to free up disk space.

Then decide how big you want your log file to be, divide that number in half, then rotate your log files the way I described. That way your log file will always be between 1/2x - x.

Or you can write a little script to take the head or tail of your file as far as you want into a new file then replace as original.
