I'm trying to write a small script using bash that essentially
archives logs to prevent logs from getting too big and take up drive
space.
man logrotate

In his case that will not work, since the program writing to the log
file has the file open (via redirection) and two programs writing to a
log file is not a good idea. If logrotate moves the log file to
logfile.1, the program will continue writing to logfile.1 since it is
writing the inode which has not changed.

In order to allow log file rotation, he has to rewrite the program
writing to the log file so that it can allow the log file to be moved.

Since logrotate already has much of the functionality that the OP
appeared to be suggesting (s)he wanted, I thought (s)he might be able
to learn from a program that already does it.

Certainly if he had a program which would allow its logs to be rotated tehn
logrotate would be the thing to use. However, his program is not of the
form that allow the logs to be rotated since he keeps the file open.
