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
