rsync script

twantrd · 01-05-2005, 07:26 PM

Hi,

Trying to write an rsync script that will rsync directories off a list of ip's contained in a file. The process of rsyncing from the list is easy but I dont quite understand how to catch if there is an error in the rsync. And if there is, skip that ip and go on with rsyncing the next ip. A section of my script is:

list=`cat list.txt | awk '{print $1}'`

for ip in $list; do
echo "IP is: $ip"
ssh $ip "(rsync -avz /home server:/backup)"
# IF rsync failed, display which ip it failed and go on with the next ip #
echo "Rsync Finished on $ip..."
done

Can anyone help me with this problem? Thank you.

what about?

Code:

if ssh $ip "(rsync -avz /home server:/backup)" ; then
      # IF rsync failed, display which ip it failed and go on with the next ip #
       echo oh dear blah blah
else
     echo "Rsync Finished on $ip..."
fi

the previous probly won't work.
I usually end up saving stderr to
a file and then checking to see
if it's got any errors in.

trouble is you can lose the context of the errors
in relation to stdout messages.

be interested if anyone knows a better way, been bugging me
for ages this sort of thing!

here's an example standalone that works...

Code:

do_it()
{

    exec 6>&2        # save stderr
    exec 2> err.log  # redirect stderr to error log

    cat <<EOF

### running:"$@"

EOF


    rsh primaappdev "$@"

    if [ -s err.log ];then   # if error log contains data

        cat - err.log   <<EOF
ERRORS:
======
EOF
    else

        : echo SUCCESS
    fi
    exec 2>&6

}

# LOOP code here
do_it date
do_it fig

Code:

billym.primadtpdev>bash  ./rsh

### running:"date"

### running:"fig"

ERRORS:
======
ksh: fig:  not found
