LinuxQuestions.org - Slackware Current using rsync

I found this after googling "slackware current rsync" (2nd page): a script to update your slackware-current tree using rsync. I'm reproducing it below for the record, in case the original site is no longer available. DISCLAIMER: I have not used this script, and cannot offer support for it; you might want to contact the author.

Also, I suggest not using ftp.slackware.com as a server; choose a mirror server instead. You can find a list of mirrors at www.slackware.com. Personally, I use www.slackware.at

Code:

# This script should (theoretically) update the slackware-current tree 

# using rsync, copy the correct directories to the iso tree, build an iso 

# image of the iso tree, and then delete the iso tree.

# This script was written by Chris Dellicker (volthead@yahoo.com)



# 12/26/02 The above description is a bit old and outdated.  Read the script

# to find out exactly what it does.  It still builds an ISO of 

# slackware-current, and keeps an up-to-date local tree of same, just does

# it a bit differently (and better) than it used to.



#This sets variables to be used by the script

SLACK=/slack                                #slackware-current directory

ISO=/slackiso                                #iso directory

BACKUP=/slackbackup                    #path to backup files to

DATE=`date +%m%d%y%H%M`                        #current date (MMDDYYHHmm)





# This says which server to use.  Comment out the one(s) you don't want.



#SERVER=ftp.slackware.com

SERVER=carroll.cac.psu.edu
