Yep, It's definitely in the path. I've tried it with and without the full path in the command line. In my haste in posting yesterday.

I forgot to mention that FTP users seem to have no problem here. I'm using vsftp as the server software. All instances of the at command are spawned as the user ftp-files, an internal user with shell privileges. Users that access the site via https however spawn all processes as the user they login as. I.E. external users with no shell privileges. Again the weird thing is that the immediate removal works at doesn't. Both means of access trigger the same script file, the only difference is the user name.

I've also noticed that depending on whether or not I use sudo for the at command itself the user under which it's spawned will change as well.

If nothing else, I've at least got to look forward to the "Brick Wall" until I get this figured out.Smilie

-----Post Update-----

It may not be right, but I've found a work around.

I had to call the script that spawns the at command via sudo. For whatever reason calling the at command directly wouldn't work sudo or not. I even tried just echoing text to a file. Nothing... Nothing in /var/log/anything. Just nothing.

Backing up one script and making the sudo call there worked. Although I still want to figure out why the direct call didn't work, I'll have to put it aside for now and finish my task.

Thanks for the input.

NAME
gksu - GTK+ frontend for su and sudo SYNOPSIS
gksu gksu [-u <user>] [options] <command> gksudo [-u <user>] [options] <command> DESCRIPTION
This manual page documents briefly gksu and gksudo gksu is a frontend to su and gksudo is a frontend to sudo. Their primary purpose is to run graphical commands that need root without the need to run an X terminal emulator and using su directly. Notice that all the magic is done by the underlying library, libgksu. Also notice that the library will decide if it should use su or sudo as backend using the /apps/gksu/sudo-mode gconf key, if you call the gksu command. You can force the backend by using the gksudo command, or by using the --sudo-mode and --su-mode options. If no command is given, the gksu program will display a small window that allows you to type in a command to be run, and to select what user the program should be run as. The other options are disregarded, right now, in this mode. OPTIONS
--debug, -d Print information on the screen that might be useful for diagnosing and/or solving problems. --user <user>, -u <user> Call <command> as the specified user. --disable-grab, -g Disable the "locking" of the keyboard, mouse, and focus done by the program when asking for password. --prompt, -P Ask the user if they want to have their keyboard and mouse grabbed before doing so. --preserve-env, -k Preserve the current environments, does not set $HOME nor $PATH, for example. --login, -l Make this a login shell. Beware this may cause problems with the Xauthority magic. Run xhost to allow the target user to open win- dows on your display! --description <description|file>, -D <description|file> Provide a descriptive name for the command to be used in the default message, making it nicer. You can also provide the absolute path for a .desktop file. The Name key for will be used in this case. --message <message>, -m <message> Replace the standard message shown to ask for password for the argument passed to the option. Only use this if --description does not suffice. --print-pass, -p Ask gksu to print the password to stdout, just like ssh-askpass. Useful to use in scripts with programs that accept receiving the password on stdin. --su-mode, -w Force gksu to use su(1) as its backend for running the programs. --sudo-mode, -S Force gksu to use sudo(1) as its backend for running the programs.
