How to do two or more rsyncs with one password?

[keith smith]

Hi Joe,

Here is a shell script I inherited.  Probably someone before me found it on a website for all I know.  I do not fully understand it however just modify the rsync= line, modify the paths= area, and replace ServerNameGoesHere with the destination server.  You may want to remove the MySql part.

I'm guessing this works because there is a key in place already.


#!/bin/bash

# sync content to off-site systems

[ -t 1 ] && v=vP
rsync=( rsync -az$v -e "ssh -p 22" --bwlimit=2000 --delete-after )

paths=(
        /home                   # main thing to get sync'd
        /etc/php.ini            # what if php.d is out of sync?
#       /etc/php.d              # sync via yum somehow?
#       /var/lib/mysql          # use replication instead
        /var/www/html           # nothing here usually
        /var/www/cgi-*          # cgiwrap and phpwrap
#       /var/lib/php/session    # sessions will break anyway
)

for path in "${paths[@]}"
do
        [ -t 1 ] && echo "$path"
        "${rsync[@]}" "$path" ServerNameGoesHere:"${path%/*}/" & [ -t 1 ] && wait
done

# sync mysql to a backup folder (replication normally handles it)
[ -t 1 ] && echo /var/lib/mysql
"${rsync[@]}" /var/lib/mysql/ ServerNameGoesHere:/var/lib/mysql-rsync/

wait
[ -t 1 ] ||
while pgrep -x rsync >/dev/null
do
  echo rsync still running!
  sleep 10
done

How can one do two or more rsyncs with entering the password just once?

Thanks Brian. That is exactly what I was looking for.

That is also a very helpful suggestion (others have recommended),
but just haven't got it done yet.
