perl reg expression help.

[Master Chief Petty Officer John-117]

Hi,
I am looking to compile a regular expression to meet the following req's if anybody hands on with perl can help

1. looking for string 'files' (in a given folder location) i.e. C:\program files\files or /home/files
2. string should match any case (upper/lower and mix)
3. string should occur at the end (whats leading is regardless)
4. if there are multiple occurences (i.e. program files\files) it should match the last one only

Many Thanks

Probably easiest to use grep. This command returns all instances of
"files" contained in any file in the current working directory:

grep files *

That should be enough to get you started. Look for 'case insensitive'
and 'word boundary' switches.
