(t)csh command line arguments issues
1. The problem statement, all variables and given/known data:

create a shell script, chExt.sh that takes one or more parameters, where the first is a desired extension and the remainder are names of files to be renamed. For each file in the command line, this script should rename the file, as above, if the file exists or print the error message described in the previous step if the file does not exist.
For example,

ls > crocodile.foo
echo bark > dingo.bar
./chExt.sh dat crocodile.foo bogusName.foo dingo.bar

should result in crocodile.foo being renamed crocodile.dat, an error message "bogusName.foo: No such file", and dingo.bar being renamed dingo.dat.




2. Relevant commands, code, scripts, algorithms:
Code:
#!/bin/csh

set ext = $1
shift

foreach file ( $*  )
# with double quotes show all to one name
# with single quotes foreach: No match.
# without quotes separate king cobra.dat into 2 files
echo "original input" "$file"
set oldName = "$file"
if ( -e "$oldName") then
set newName= (`echo "$oldName" | sed "s/\(.*\)\..*/\1/"`)
set newName = "$newName"."$ext"

if ("$file" != "$newName") then
mv "$file" "$newName"
endif
else
    echo "$file"": No such file"
endif


3. The attempts at a solution (include all code and scripts):
Line 6 : foreach file ( $* )
I need it to be able to read in 'cpp' 'file.dat' 'king cobra.dat'
as 3 variables, but i can only get it to do 'king' and 'cobra.dat'
i tried putting double quotes around "$*" in my foreach but that causes the variable to be 'file.dat king cobra.dat' as one long variable name


4. Complete Name of School (University), City (State), Country, Name of Professor, and Course Number (Link to Course):
Old Dominion University, Norfolk, Virginia, USA, Prof. Zeil, CS252<http://www.cs.odu.edu/~cs252/>


please help ASAP, it's due by tonight and i've been stuck on this for days now.
