Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have an issue with detecting if a file that begins with "SYS_0" exists. We have a Windows based database that is backed up to a linux server (Debian). The file names are similar but with a date suffix. What I need to do is confirm that a particular backup file - or set of files - is present (meaning backup completed) and then process. Script follows:
if [ -f $FILE ]; then
rm -f /media/Backup/SYS_3*
rename -f 's/SYS_2/SYS_3/' /media/Backup/SYS*
rename -f 's/SYS_1/SYS_2/' /media/Backup/SYS*
rename -f 's/SYS_0/SYS_1/' /media/Backup/SYS*
The problem is that multiple SYS_0... files can exist. The script works fine if only one exists. What am I doing wrong?
Thanks for any help.
Thanks - I tried logrotate but because of file naming, I had problems on the Windows server. I have to maintain the specific name(s) following the "SYS_X". The script I posted works except when there are multiple instances of SYS_0.
Is there any way to determine the existence of that prefix?
