Also, can you (really, really) ask Professor Zeil why he is teaching you this crap?

I mean... C-Shell is so 1980's! Oh, and it's useless.
I have no idea why he chose c-shell. We could also use sh but csh looked easier.

This ends with Illegal variable name.

Code:
#!/bin/csh


while ( $# > 0 )
        echo "got $1"
        shift
end


as well as my full code with the while loop
Code:
#!/bin/csh

set ext = $1
shift

while ( $# > 0 )
# comments refer to issues with the forreach loop
# 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" "$1"
set oldName = "$1"
if ( -e "$oldName") then
set newName= (`echo "$oldName" | sed "s/\(.*\)\..*/\1/"`)
set newName = "$1"."$ext"

if ("$1" != "$newName") then
mv "$1" "$newName"
endif
else
    echo "$1"": No such file"
endif
shift
end

shells

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The following default shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/ksh93, /bin/pfcsh, /bin/pfksh, /bin/pfsh,
       /bin/sh, /bin/tcsh, /bin/zsh, /sbin/jsh, /sbin/sh, /usr/bin/bash, /usr/bin/csh, /usr/bin/jsh, /usr/bin/ksh, /usr/bin/ksh93, /usr/bin/pfcsh,
       /usr/bin/pfksh, /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh, and /usr/sfw/bin/zsh. /etc/shells overrides the default list.

       Invalid shells in /etc/shells could cause unexpected behavior, such as being unable to log in by way of ftp(1).
