@Don Cragun
Thanks for your advice, unfortunately most of it is completely over my head - hence why I post on here for help - I am not an IT professional Smilie

The idea is that a pdf will be produced by front-of-house staff from a word document that is populated from an MS Access application Smilie

using a virtual cups-pdf printer on my ubuntu server. The pdf will then need to have the characters added by the pdf printer removed, the creation date added and moved to a new directory. From the new location the pdf will be edited by a user (me) on a tablet pc (probably an iPad Smilie

) and then attached back to the MS Access record. I was planning to run the script that alters the pdf filename every 30secs or so as a cron job from a unprivileged user home directory. Hopefully this all makes sense?

I am open to better suggestions if you have any Smilie

Thanks

OK. Back to basics:
1. Will all of the files you want to rename be in the same directory? If so, what is the name of that directory? If not, what are the names of all of the directories that will contain pdf files you want to rename?
2. What is the name of the directory where you want to place the renamed pdf files?
3. When you run the command:

Code:

uname -a

what is the output?

If you want a script to run every 30 seconds, cron won't be sufficient; its finest granularity is 1 minute. And, if the system is busy, you could end up having two copies of your script running at the same time. If you run a script to rename files every few minutes after a file is converted, the likelihood that the current date and the file's creation date are different is pretty low (especially if the front end people who create the pdf files don't work between 11pm and 1am).

cupsfilter

cupsfilter(8)							    Apple Inc.							     cupsfilter(8)

NAME

       cupsfilter - convert a file to another format using cups filters

SYNOPSIS

       cupsfilter [ --list-filters ] [ -D ] [ -U user ] [ -c config-file ] [ -d printer ] [ -e ] [ -i mime/type ] [ -j job-id[,N] ] [ -m mime/type
       ] [ -n copies ] [ -o name=value ] [ -p filename.ppd ] [ -t title ] [ -u ] filename

DESCRIPTION

       cupsfilter is a front-end to the CUPS filter subsystem which allows you to convert a file to a specific format, just as if you had  printed
       the file through CUPS. By default, cupsfilter generates a PDF file. The converted file is sent to the standard output.

OPTIONS

       --list-filters
	    Do not actually run the filters, just print the filters used to stdout.

       -D   Delete the input file after conversion.

       -U user
	    Specifies the username passed to the filters. The default is the name of the current user.

       -c config-file
	    Uses the named cups-files.conf configuration file.

       -d printer
	    Uses information from the named printer.

       -e   Use every filter from the PPD file.

       -i mime/type
	    Specifies the source file type. The default file type is guessed using the filename and contents of the file.

       -j job-id[,N]
	    Converts document N from the specified job. If N is omitted, document 1 is converted.

       -m mime/type
	    Specifies  the  destination  file  type.  The  default  file type is application/pdf. Use printer/foo to convert to the printer format
	    defined by the filters in the PPD file.

       -n copies
	    Specifies the number of copies to generate.

       -o name=value
	    Specifies options to pass to the CUPS filters.

       -p filename.ppd
	    Specifies the PPD file to use.

       -t title
	    Specifies the document title.

       -u   Delete the PPD file after conversion.

EXIT STATUS

       cupsfilter returns a non-zero exit status on any error.

ENVIRONMENT

       All of the standard cups(1) environment variables affect the operation of cupsfilter.

FILES

       /etc/cups/cups-files.conf
       /etc/cups/*.convs
       /etc/cups/*.types
       /usr/share/cups/mime/*.convs
       /usr/share/cups/mime/*.types

NOTES

       Unlike when printing, filters run using the cupsfilter command use the current user and security session. This may result in different out-
       put or unexpected behavior.

EXAMPLE

       The following command will generate a PDF preview of job 42 for a printer named "myprinter" and save it to a file named "preview.pdf":

	   cupsfilter -m application/pdf -d myprinter -j 42 >preview.pdf
