You can just "mv" it to a new name, a new file will be created.

What I do is keep a hard link to "history" named "history.YYYYMM".
At the start of the month I can simply delete "history".  In this case
I also create a new "history" myself so I can make a new hard link.

I do this automatically with a cron job:

0 0 1 * * cd /exports/condor/spool && rm history && touch history && ln history $(date +history.\%Y\%m)
