# logrotate.ps1
# - renames and archives log files
# v1.15.1228 - (c) by ibi c/o flatbyte.com
#
# parameters are read from logrotate.csv in the same directory
#
# logrotate.csv looks like this:
## ServiceToStop,ServiceToStart,PathFileMask,RenameLog,ArchiveDir,DaysToKeep
## W3SVC,W3SVC,d:\logs\php-error.log,1,d:\logs\archive,3
## ,,v:\logs\rsFOZZIE*.log,0,d:\logs\archive,7
#
# ServiceToStop:
# which service should be stopped before processing log files? short name of service used by cmd.exe's "net stop"
# ServiceToStart:
# which service should be started after processing log files? short name of service used by cmd.exe's "net start"
# --- NOTE: service names for starting/stopping are independent, but script needs admin-rights to do so.
# PathFileMask:
# which file names are to be processed? wild card like "*" or "?" are ok.
# RenameLog:
# bool for renaming files: 1- rename, 0- don't rename. 
# --- CAUTION: if files are not moved and wild cards are used subsequent runs will rename them again!
# ArchiveDir
# path where archived files are moved. NOTE: path *must* exist.
# DaysToKeep
# number of days, older files will be processed/moved, i.e. "7"=archive files older than 7 days
