Subject: pws-19: comparing (k) and (I) for hashes
Date: Tue, 25 May 1999 16:23:50 +0400 [thread overview]
Message-ID: <014401bea6a9$71f5f1a0$21c9ca95@mow.siemens.ru> (raw)
>From manual I got the impression, that ${(k)...} and ${...[(I)...]} do the
same - both return the keys of matching elements. Cf. (I) description:
`I'
like ``i', but gives the index of the last match, or all possible
matching keys in an associative array.
In case of parameters hash, the keys are parameter names, so
bor@itsrm2:~%> print -l ${(k)parameters[(R)scalar*]} | grep foo
foo
bor@itsrm2:~%>
(as expected), but
bor@itsrm2:~%> print -l ${parameters[(I)scalar*]} | grep foo
bor@itsrm2:~%>
What do I do wrong?
