    <p>I am currently writing a bash shell script to transfer the latest revision of our svn repository to a webserver. This is done using svn export to server A and rsync'ing it with the webserver, a special user (called sync_user) was created with sufficient permissions on each side (server A and the webserver) to perform these updates. The script uses "su sync_user" to perform the svn export and rsync as sync_user : </p> <pre><code>export -f sync_section su sync_user -c "sync_section $source $tmp $dest" </code></pre> <p>where sync_section is a function in the script:</p> <pre><code># critical section which performs the actual website update (export &amp; sync) # takes 3 parameters: source, tmp, dest function sync_section { source=$1 tmp=$2 tmp_old=$tmp"_old" dest=$3 #enter critical section set -e # export to temp folder on server A svn export -q --force $source $tmp --native-eol LF # rsync with remote live website folder. rsync -avzhiO $tmp $dest # clean up rm -rf $tmp_old mv -f $tmp $tmp_old # exit critical section set +e } </code></pre> <p>The idea is that everyone who has permissions to update/sync the webserver knows the sync_user's password, thus can enter into the "su sync_user" section. </p> <p>Sounds good in theory but rsync is not happy with this setup and gives me the following error message: (user_x is the user calling the script)</p> <pre><code>#### rsync output: building file list ... rsync: pop_dir "/home/user_x" failed: Permission denied (13) rsync error: errors selecting input/output files, dirs (code 3) at flist.c(1314) [sender=2.6.8] </code></pre> <p>After some googeling I found out that the problem I am having is caused by rsync as it requires the sync_user to have full access permissions on the script caller's home directory. Is that correct? and if so why? and is there a work-around for it? </p> <p><strong>Note:</strong> The home directory of the user is not used at all in the script. Only /tmp/ on server A and /var/www/vhosts/ on the webserver are used. </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
