RotateBackup is a Perl script that eliminates old backup files, intended to be utilized from a cron job. It is easy to use and simplifies backup file removal.
In general, Perl is a flexible programming language formulated by Larry Wall back in 1987. This dynamic language is quite versatile and draws traits from different other programming languages such as C, shell scripting (sh), AWK, sed and Lisp. Perl is widely favored owing to its robust and powerful text processing capabilities, which trumped any other Unix tools present back in the day.
Therefore, if you are looking for a reliable way of systematically deleting old backup files at your convenience, this script should be your go-to option. Additionally, if you have familiarity with Perl, you will enjoy the customizable features of the script.
