Does that imply in your case, Solaris' /bin/sh does not support these

snippet form "man sh":
${name#pattern}
${name##pattern}
If pattern matches the beginning of the value of parameter name,
the matched text is deleted from the result of substitution. A
single `#' results in the shortest match, and two of them result
in the longest match.
${name%pattern}
${name%%pattern}
Like ${..#..} substitution, but it deletes from the end of the
value.
