As far as I know, it should be supported by a POSIX 'sh'[1]:
---8<---
${parameter##word}
Remove Largest Prefix Pattern. The word shall be expanded to produce a
pattern. The parameter expansion shall then result in parameter, with
the largest portion of the prefix matched by the pattern deleted.
---8<---
Whether other shells support it or not... I don't know.
Cheers,
Ferdy
