tcsh isn't installed on linux by default. It's optional.

Beyond that, it's not "weak", except in the ways tcsh has always been "weak" -- buggy, unfixably flawed(Bill Joy later confessed he "wasn't very good at programming" when he designed the csh), and a poor programming language in general.

Is this true ...if so should moving to BASH a better option ...
Bourne shell in general would be a better option. You don't have to program for BASH, it's possible to make bourne scripts that'll work in many places.

What interactive things are you worried about, exactly?

BASH has easy command-editing(left-right arrows and delete do what you expect), a decent command history accessible with up/down/pgup/pgdn keys, tab completion, aliases...

BASH aliases work a little differently than tcsh ones. You can't have parameters in the middle of them. BASH functions are a better replacement if you need that complex kind of arrangement:

Code:
function asdf
{
        echo a $1 b $2 c
}

# This would echo a x b y
asdf x y

ctrlaltdel

CTRLALTDEL(8)						       System Administration						     CTRLALTDEL(8)

NAME

       ctrlaltdel - set the function of the Ctrl-Alt-Del combination

SYNOPSIS

       ctrlaltdel hard|soft

DESCRIPTION

       Based  on examination of the linux/kernel/sys.c code, it is clear that there are two supported functions that the Ctrl-Alt-Del sequence can
       perform: a hard reset, which immediately reboots the computer without calling sync(2) and without any other preparation; and a soft  reset,
       which sends the SIGINT (interrupt) signal to the init process (this is always the process with PID 1).  If this option is used, the init(8)
       program must support this feature.  Since there are now several init(8) programs in the Linux community, please consult	the  documentation
       for the version that you are currently using.

       ctrlaltdel is usually used in the /etc/rc.local file.

FILES

       /etc/rc.local

SEE ALSO

       simpleinit(8), init(8)

AUTHOR

       Peter Orbaek (poe@daimi.aau.dk)

AVAILABILITY

       The ctrlaltdel command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
