${parameter/pattern/string}
   Pattern substitution.  The pattern is expanded to produce  a  pattern  just  as  in  
   pathname expansion.  Parameter is expanded and the longest match of pattern against
   its value is replaced with string.  If pattern begins with /, all matches  of  pat‐
   tern are replaced with string.  Normally only the first match is replaced.  If pat‐
   tern begins with #, it must match at the beginning of the expanded value of parame‐
   ter.   If  pattern begins with %, it must match at the end of the expanded value of
   parameter.  If string is null, matches of pattern are deleted and the  /  following
   pattern  may  be  omitted.   If  parameter is @ or *, the substitution operation is
   applied to each positional parameter in turn, and the expansion  is  the  resultant
   list.   If parameter is an array variable subscripted with @ or *, the substitution
   operation is applied to each member of the array in turn, and the expansion is  the 
   resultant list.
