to extract all the part of the filename before a particular word in the filename

Hi All,
Thanks in Advance

I am working on a shell script. I need some assistance.

My Requirement:

1) There are some set of files in a directory like given below

OTP_UFSC_20120530000000_acc.csv
OTP_UFSC_20120530000000_faf.csv
OTP_UFSC_20120530000000_prom.csv
OTP_UFSC_20120530000000_subs.csv

I want to check if all thes files exists in the directory

the keywords are acc.csv, faf.csv, prom.csv, subs.csv
apart from this all the other things vary time to time (like the field seperator used in the file (can be.,-,_ etc) and the names OTP UFSC will vary.

2) if the file does not exist I have to touch (Create a empty file by that name)
Example : Imagine the file OTP_UFSC_20120530000000_acc.csv doesnot exist
in the directory
I have to search first if a file *acc.csv exist in the directory or not. If not i will extract the prefix (anything before acc.csv in this case OTP_UFSC_20120530000000_) from an existing file which is common to all the files in the directory
and create a file OTP_UFSC_20120530000000_acc.csv

Smilie

Any suggestions and help

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       processcsv.py - process virt-top CSV files

SUMMARY

	virt-top --csv data.csv
	processcsv.py < data.csv

DESCRIPTION

       virt-top is a top(1)-like utility for showing stats of virtualized domains.

       processcsv.py is a simple Python script that post-processes the output of "virt-top --csv".

       It is used like this:

	virt-top --csv data.csv
	processcsv.py < data.csv

       The second command will overwrite the following files in the current directory:

       "global.csv"
	   This contains the global (host) statistics columns from the CSV file.

       "domainNN.csv" (multiple files)
	   For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file.
