The problem is the .'s
I want to ignore all .'s until the final one (not just for this string).
You are saying you want the final answer to _include_ the dot? That is an unreasonably complicated thing to try to do for not enough gain. It's possible with sed, but you're working too hard to figure out that sed/regex syntax, and by forking a process to run sed, also making the computer work too hard.
The simple and practical answer is just to add the dot back in yourself like this:
One reason for wanting the dot is that you can reconstruct the entire string by concatenation: "path + name + extension". If the extension is missing, doing "name + dot + extension" would not get the original string. Msdos libraries typically included routines to do all that. Linux aparently not, because extensions have (almost) no meaning. Sometimes I create my own path manipulation binary (in pascal). - -- Cheers, Carlos E. R.
