bug with **/ syntax?

bug with **/ syntax?

[Matthew Braun]

I'm trying to get the behavior of ksh's */, which according to the zsh
man page, looks like you should use **/ to get that behavior.  To me it
looks like **/ is really acting like ***/.

Examples below.

So is this a bug or am I not reading the man page correctly?

Matthew.

That is correct behaviour:

A pathname component of the form
.BI ( foo /)#
matches a path consisting of zero or more directories
matching the pattern foo.
As a shorthand,
.B **/
is equivalent to
.BR (*/)# .
Thus:
.RS
.PP
ls
.BI (*/)# bar
.RE
.PP
or
.RS
.PP
ls
.BI **/ bar
.RE
.PP
does a recursive directory search for files named bar, not following
symbolic links.  For this you can use the form
.BR ***/ .
