man bash:
Quote:
${parameter#word}
${parameter##word}
Remove matching prefix pattern. The word is expanded to produce a pattern just as in pathname expansion. If the pattern matches the beginning of the value of
parameter, then the result of the expansion is the expanded value of parameter with the shortest matching pattern (the ``#'' case) or the longest matching pat”
tern (the ``##'' case) deleted.
The inner
${FN%%[[:alpha:]]*} removes all chars from the first alpha to string end, then
${FN#...} uses the result to remove the leading digits, no matter how many.
