Rsync plugin to many local wordpress installs via script or cli

Question

I am maintaining a large number of wordpress installs on a production server, and we are looking to deploy InfiniteWP for managing these installs. I am looking for a way to script the distribution of the plugin folder to all of these installs.

On server wp-prod, all sites are stored in /srv/sitename/site/ The plugin needs to be copied from ~/iws-plugin to /srv/sitename/site/wp-content/plugins/

Here's some pseudo code to explain what I need to do:

array dirs = <all folders in /srv>
for each d in dirs
   if exits "/srv/d/site/wp-content/plugins"
     rsync -avzh --log-file=~/d.log ~/plugin_base_folder /srv/d/site/wp-content/plugins/
   else
     touch d.log
     echo 'plugin folder for "d" not found' >> ~/d.log
   end
end

I just don't know how to make it happen from the cli or via bash. I can (and will) tinker with a bash or ruby script on my test server, but I'm thinking the command-line-fu here on SF is strong enough to handle this issue much more quickly than I can hack together a solution.

Thanks!

Answer 1

ok here's some bash.. first, to get a list of all sites with plugin directories you can use globbing and ls -d (ie don't descend directory, give directory entry only)

e.g.:

for i in `ls -d /srv/*/site/wp-content/plugins`
do
   #whatever rsync command you want to do, $i will evaluate to the directory name
   e.g rsync -avzh /source/plugindir $i
done

#second pass to find all cases where the plugins directory does not exist.

LOGFILE = "/some/log"
echo 

    for i in ` ls -d /srv/*/site/wpcontent`
    do
      if [ ! -d ${i}"/plugins" ]
      then
         echo ${i}"is evil" > $LOGFILE
     fi 
    done

I ignored the part about having specialized rsync logfiles for each directory.. I wasn't sure what you meant by the path ~/d.log. you could do something with sed to change the slashes to dashes if you really wanted to have separate log files for rsync, or you could use awk and split out just the site name and use that as a base name for the log file. eg:

LOG=`echo $i | awk -F/ '{print $2}'`

Answer 2

I had this written a few hours after the quetion was posted, but don't have the rep andwer my own question without waiting, so I'm posting it now. I feel like cli commands or a bash script could do this much more concisely, but this is what I wrote to do the job and it's pretty clear (even before I documented it so heavily)

Any feedback on this or alternative solutions will be greatly appreciated:

    end
