bash scripting - largest # file extension
I have files named bleh.1, bleh.2, bleh.3, bleh.4... bleh.10, etc. that are being created, and want to track their progress. Is there a way to find the largest extension (1, 2, 3, ... 10, etc) of the set of files named "bleh", then be able to use that extension to look at that file (if 10 is the largest then view bleh.10)?
note- the newest files will have the largest extension, so maybe there's a way to do it with some sort of search for the newest file, then grab its extension somehow, and use that extension with the set of files named "bleh" (ie: The newest file found is xyz.10, so look at bleh.10)
