Finding & Moving Oldest File by Parsing/Sorting Date Info in File Names
I'm trying to write a script that will look in an /exports folder for the oldest export file and move it to a /staging folder. "Oldest" in this case is actually determined by date information embedded in the file names themselves.

Also, the script should only move a file from /exports to /staging if staging is empty; if there's already a file in /staging then the script would exit without doing anything.

Here's an example of what the folders and files might look like:

/exports
job1_Friday_05302008.xml
job1_Monday_05262008.xml
job1_Monday_06022008.xml
job1_Thursday_05292008.xml
job1_Tuesday_06032008.xml
job1_Wednesday_05282008.xml

/staging

In this case, because /staging is empty, the script should move /exports/job1_Monday_05262008.xml to /staging. The next time the script runs it should exit if /exports still contains job1_Monday_05262008.xml, otherwise it should move job1_Wednesday_05282008.

Also, the "job1" prefix is static.

I've got a script that uses ls and cat to loop through file names and parse out the date information but i'm getting bogged down with how to handle the results and i'm starting to think i might be going down the wrong path...

Any suggestions would be appreciated

GNOME-XML(1)							       1.1.0							      GNOME-XML(1)

NAME

       xml-config - script to get information about the installed version of GNOME-XML

SYNOPSIS

       xml-config [--prefix[=DIR]] [--libs] [--cflags] [--version] [--help]

DESCRIPTION

       xml-config  is  a  tool	that  is  used to determine the compile and linker flags that should be used to compile and link programs that use
       GNOME-XML.

OPTIONS

       xml-config accepts the following options:

       --version
	       Print the currently installed version of GNOME-XML on the standard output.  Add the --static option to print the linker flags  that
	       are necessary to statically link a GNOME-XML program.

       --libs  Print the linker flags that are necessary to link a GNOME-XML program.

       --cflags
	       Print the compiler flags that are necessary to compile a GNOME-XML program.

       --prefix=PREFIX
	       If  specified,  use  PREFIX  instead  of  the  installation  prefix that GNOME-XML was built with when computing the output for the
	       --cflags and --libs options. This option must be specified before any --libs or --cflags options.
