It's quite simple, actually. In `${name}' substitutions, the `name'
may also be another substitution. The outer one will then work on the
result of the inner one (of course they can be nested as deeply as you 
want). So the `${(C)i}' is a parameter substitution with a flag, the
`(C)'. Such flags not supported by other shells, so I think this is
what really irritates you. Zsh has several such flags, some are
rather baroque, but many are quite useful, see the `Parameter
Expansion' section in the docs (in the `zshexpn.1' man page if you use 
the manual). Sorry, there are too many flags to explain all of them
here.
Anyway, the `${(C)i}' yields the contents of the parameter `i'
capitalized. This string is then used by the `${...:s/Mp3/mp3}' which
just replaces every `Mp3' with `mp3', of course.

Bye
 Sven

Could someone explain this one to me, piece by piece? Obviously,
s/Mp3/mp3 does a substitution but what is ${${(C)i}} all about?

Hello all,

It shouldnt bother you, guys, to recieve some too simple questions from time to time hen? :)

I tried the solution :

for i in *.ps; do
mv  $i ${${(C)i}:s/ch/chap/}
done

I had these .ps files :

evol.ch2.37p.ps evol.ch3.54p.ps evol.intro.3p.ps  evol.ch1.13p.ps

my zsh command changed them to :

Evol.Evol.Ch3.54p.Ps  Ch1.13p.Ps Evol.Ch2.37p.Ps Evol.Intro.3p.Ps

I am using ZSH_VERSION=3.1.2 on solaris 7.

Yes, sorry, didnt read in man page on this, just hoped to learn this one w/o any efforts :)

Thanx.
Mohamed.

Thanks a lot! I've seen "C" in the manual but I thought it would capitalize
all letters. That was a wrong thought! Thanks again!

It is far better than the perl RE that I used:
s/(?:^|(?<=\s))(\w)(\w+)(?:$|(?=\.)|(?=\s))/uc($1).$2/ge

:-)

Upper case

[Mircea Damian]

Hello,

I was wondering yesterday if there is a simple way to rename all my song
files(mp3) from


name with spaces.mp3   ->  Name With Spaces.mp3

with something like:
for i in *.mp3; do 
mv -v $i (UNKNOWN_PART_TO_ME)
done


I tried using sed there but with no luck. Can anyone give me a clue here?
