I just discovered zmv this morning.

To test it i have created a few files.

test1.txt test2.txt test3.txt

I'm trying to rename them with zmv I'd like to get this output:

test-1.txt test-2.txt test-3.txt

when I try to use wildcards I get an error message:

zmv '(*)([0-9]{1,})(.txt)' '$1-$2$3'
zmv: error: number of wildcards in each pattern must match

Am i doing something wrong (answer has to be yes :) )

If the first parameter is a regular expression and it is greedy by default, try ([^0-9]*) as the first part maybe. –  Oliver Salzburg Mar 14 '12 at 12:04
    
What zsh version? Do you have zmv aliased? –  Gilles Mar 14 '12 at 22:38
    
zsh 4.3.9, autoload -U zmv, alias zmv="noglob zmv -W" –  Yannick Schall Mar 14 '12 at 23:26

Do you only want to add a - to the filename? Try it like this:

zmv -n 'test(*).txt' 'test-${1}.txt'

The -n switch shows you what would happen without really performing any action.

Tried just that, but I get the same error message. I'm running zsh 4.3.9 on osx. not sure if it changes anything. –  Yannick Schall Mar 14 '12 at 12:56
