diff between tcsh and csh -f

Hello

Am very new to linux/unix, workin in it since 10 days only. I had started with bash and now I need to work in tcsh. I have changed shell for my user profile using 'chsh'

I use gedit for script writing. Now in the first line if I write #!/bin/tcsh i get d msg
/home/usr/.cshrc: No such file or directory.

If I use #!/bin/csh -f
the script runs

Am confused if I'm still in tcsh or not. Please help.

And also please guide me to a good reference. I have been to TCSH(1) Astron 6.10.01 (26 April 2001) TCSH(1) but frankly I could not understand anything. I started with linux by refering to :: commandlinux :: and that was very helpful.

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). FILES
