Regarding the
${parameter/pattern/string}
${parameter//pattern/string}
discussion on the man page:
You don't mention what if pattern is null.
Seems that will never match.
Anyway, no way to
$ set aa bb cc
$ echo ${@....}
so that one gets all parameters to have a string appended,
e.g. aa.t bb.t cc.t
One must sacrifice at least one character in "pattern". No way to
destroy less than one character.
One must do
$ ls|sed s/$/.t/|xargs make -n
as there is no pure bash single shortcut to eliminate the pipes.
Brace Expansion not employable here either.
