topaz hum 8-) | Code :
- ${parameter/pattern/string}
- ${parameter//pattern/string}
- 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. In
- the first form, only the first match is replaced. The second form causes all matches of
- pattern to be replaced with string. If pattern begins with #, it must match at the
- beginning of the expanded value of parameter. 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 substi-
- tution 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 sub-
- stitution operation is applied to each member of the array in turn, and the expansion is
- the resultant list.
