After testing the above script, and had no output for a KMail folder, I realised it is not recursive. There are sub-folders like ..

/cur

/new

/tmp

That is why it hasn't been working for me. :D

Once I specified the exact path, the pattern worked fine, and I was able to push out all the filenames. It totalled 591 which is what I expected. Then wrote a script to compare that output with another "ls". The "culprit" file turned out to be one with a filename of "1232706568.2627.1XNmk~:2,S". It was from 2008; possibly KMail had a hiccup back then and wrote a filename with a "tilde" in it. Will rename the file and get rid of the tilde in the filename (and any others).

The issue with recursion was also true for the sub readMessageFilenames, in that it doesn't do a recursive search. Once I set it to the exact pathname, the pattern worked fine. Although that means I have to run it for every sub folder. I did try adding "-r" to grep { -f "$PATH/$_" && /^([0-9][\w.:,=\-]+)$/ } but got an error. Thanks for all your help. :)
