Problem here:

    % vi *(.om[$1])         
    zsh: bad math expression: operand expected at `'
    % 

Please advise. My environment is:

    % echo $ZSH_VERSION     
    4.3.17                  # this host is debian 7.2 (debian stable)
    % setopt | sort | column
    allexport               interactive             nobgnice
    autocd                  interactivecomments     nohup
    correctall              longlistjobs            nonomatch
    extendedglob            markdirs                pathdirs
    globdots                menucomplete            pushdsilent
    histignoredups          noautolist              shinstdin
    ignoreeof               nobeep
    %

I think you want

  vi *(.om[1])

or if you wanted to be really different

  vi *(.Om[-1])

Otherwise you're substituting a positional parameter, which you don't
want.  The error you got comes from it being empty, so there's no
number, which is what it's complaining about, slightly cryptically.

Valodim,
Whoops yes I carelessly borrowed that from my .zshrc where I have a 
function which allows me specify more options

function vew()
{
# name : vew
# description : vi newest file
# or nth newest file if a numeric parameter
# or newest file with $1 string in name
if [ $# -gt 0 ]
then
   if [[ "$1" == [0-9] ]]
   then
   gvim.exe *(.om[$1]) &
   else
   gvim.exe *$1*(.om[1]) &
fi
else
gvim.exe *~vssver.scc(.om[1]) &
fi
}

Hi

Noticing that a previous ZSH Daily Tip Twitter feed had ceased in 2010 I 
have started a new one

https://twitter.com/dailyzshtip

I hope it will help popularize our favorite shell.

It will feature day-to-day practical stuff such as

vi *(.om[$1])   # vim newest file

Any tips, advice or retweeting welcome!
