Recursive file size listing output to excel

by on Dec.30, 2009, under Admin, Batching, Scripting, vbscript

Today I had to find all JPG files over a certain size in a large directory tree of a few thousand images, to find some poorly compressed jpg’s, fix the compression, and replace them on a website. Todays cavaet, the CMS is pretty weak and only lets you update 1 image at a time, so you can’t just blindly resave everything and reupload, todays Second cavaet, I dont have server level access to said website, so all the normal automated ways are out of luck.

joy.

So I found a little snip of code online, and threw a pretty simple hack job together to narrow the scope some. (PS: If you do end up doing any vbscript, I’d suggest VbsEdit for an IDE)

Anyway! the code:

It searches through a directory tree of your choosing
for any file matching the filetype: “jpg”
that is above a size threshold: fileSizeThreshold (In this case, 2kb.. so essentially everything)
and outputs it into an excell sheet with full path and size information
so that you can easily Sort, Filter, Delegate, or use as data for further automating!

process execution across a network

by on Dec.02, 2008, under Admin, Batching

A couple simple tricks you can do with the remote process execution of the Slave Utils for fun. (Also corresponding commandlines for use with the psexec, which is what the slave utils is batching

you can start a remote command line on any of the machines in your list simply by doing a cmd.exe in the ‘ProcessToStart’ line.. its a small thing, but its helpful for certain things.. ie: copying files from one remote machine to another remote machine.. its *MUCH* faster if you do something like that FROM one of the remote machines, and skip the middleman.

How to start VNC on a remote machine, and have it work interactively… when you’re not allowed to install it as a service! (Read: Our IT uses its own copy of vnc that we aren’t allowed to Co-Opt for our own uses.. so we end up with 2 copies running!)

Apparently its tricky to run interactive remote processes that are allowed to interact with the desktop under full local privileges?! Go figure. Anyway, This is what you would enter to launch the vnc with the same privileges as if you were at that computer and hit the shortcut.

cmd.exe /c start “c:\program files\Realvnc\winvnc\winvnc.exe” “c:\program files\Realvnc\winvnc\winvnc.exe”

what this converts to in actual command line is something along the lines of:

psexec \\computer -i -d -u DOMAIN\Login -p password cmd.exe /c start “c:\program files\Realvnc\winvnc\winvnc.exe” “c:\program files\Realvnc\winvnc\winvnc.exe”

so it used the login and pass to launch the remote cmd.exe, but then used the local system privileges with the start command. allowing it to have full network and desktop interaction privileges.

More to come later.
