Automatic SVN synchronization with UUID autocopy
#!/bin/bash
# autosvnsync.sh is a tool for automatically synchronizing/mirroring SVN repositories.
# By default, the script assumes that you have configured a "syncuser" account on the SRC and DEST servers,
# and that you are running the script as "syncuser" on the DEST server (presumably behind a firewall).
#Remote SVN info
SVN_HOST="syncuser@example.com" #User and host, for SSH - alternatively, you can use ~/.ssh/config to specialize something
SVN_LOC="data/svn"
SVN_REPO="svn+ssh://$SVN_HOST/$SVN_LOC"
#Local SVN info
SYNC_LOC="/data/svnsync"
#Retrieve the list of repositories and UUIDs from the remote server
REPOS=`ssh $SVN_HOST 'for uuid_file in \`find /$SVN_LOC -type f -name uuid\`; do echo \`echo $uuid_file | cut -f4 -d'/'\`,\`cat $uuid_file\`; done'`
# refresh_repo function
# Example:
# refresh_repo $REPO $UUID $SVN_LOC
#
# Note: I'm fairly certain that it is simply pulling the variables from the environment names, and not importing them
# into the scope. So that means that strictly speaking, I should be using $1/$2/$3/$4 notation. I think.
# However, for the sake of readability, I am leaving it as-is.
