Hi, can any zsh users' tell me what is wrong with the following
function:
------------------------------------------------------------------------------
function del() {
   if (($# == 0)) {                            
      echo "usage: del [filename]..."
   } elif (($# == 1)) {
      echo hahaaha
   } else {
      echo foobar....
      mv $* /.trash
   }

Quote:}

------------------------------------------------------------------------------
According to the man page, the syntax of the conditional statements is
correct. so what is wrong here ? is it w/ the function ?

here is the error I got:

You need to put a pair of "( " and " )" around arithmetic evaluation
"(($# == 0))" if you use c-like "if", like this:

function del() {
   if ( (($# == 0)) ) {                        
      echo "usage: del [filename]..."
   } elif ( (($# == 1)) ) {
      echo hahaaha
   } else {
      echo foobar....
      mv $* /.trash
   }

But I would prefer

function del() {
   if (($# == 0)); then
      echo "usage: del [filename]..."
   elif (($# == 1)); then
      echo hahaaha
   else
      echo foobar....
      mv $* /.trash
   fi

or

function del() {
   if [[$# -eq 0]]; then
      echo "usage: del [filename]..."
   elif [[$# -eq 1]]; then
      echo hahaaha
   else
      echo foobar....
      mv $* /.trash
   fi

Have you tried simply setting up an alias?  In csh, it's simply:

alias rm 'mv !* ~/.trash'

Maybe easier....

maybe not....
