I wanted to use the simple if(-f <file name>) to find if a file exists.
However, I have a problem.
I am getting data about the files names from a database where any letters will all be in upper case.
The actual files names may have some but not all of the letters in lower case.
There can be a mixture of upper and lower case letters in each file name.
There is not a problem that there will be two files names that are the same except for the
case of the letters.
Can I use a modified form of the if, if so what is it?
If not what is the best way to find out if the file exists?
I feel there must be a simple solution but so far trials and books have failed!
