printing arrays and index

printing arrays and index

[zzapper]

Hi,
I'm using

print -C 1 $filessubject

To display the contents of the above array one entry per line

(thanx to this a previous posting in this NG)

I know want to precede each array entry with it's index number 1,2,3, etc

how do?

I was sort of puzzled by why that was suggested.  "print -l" (that's a
lowercase L, not a one) has the same effect, and works in a lot more
versions of zsh (the -C option is a very recent addition).

The most obvious way is:

	print -l $filessubject | cat -n

But something like this works too:

	i=0 eval print -l '$((++i))\ '${(q)^filessubject}

If you use 'setopt ksharrays' then change that to $((i++)).
