Hey all,
      I would like to know if there is a "general" or typical .login and .cshrc I can take and modify for use
on my school (system 5) unix account.  I am currently in a ksh., and want to upgrade to the tcsh.
                                                                                  thanks in advance,  
                                                                                  gs01web@panther.gsu.edu
                                                                                   Evan

# This is the default standard .login provided to csh users.
# They are expected to edit it to meet their own needs.
#
# The commands in this file are executed when a csh user first
# logs in.  This file is processed after .cshrc.

# $Revision: 1.8 $

# Set the interrupt character to Ctrl-c and do clean backspacing.
alias l ls -la
alias rm rm -i
alias del rm -i

alias mail Mail
alias wipe "'rm' -r"

if (-t 0) then
    stty intr '^C' echoe

# Set the TERM environment variable

# Set the default X server.
if ($?DISPLAY == 0) then
    if ($?REMOTEHOST) then

Hmm. I think that upgrading from the ksh to the tcsh is an oxymoron. However...

There is no such thing as typical initialisation files but maybe a few guiding principles will help you.

Remember that .cshrc is executed every time you start up a new C shell, whether that is by typing csh at the command line, logging in, or executing a csh command script. Of course you can avoid executing .cshrc in a script by starting it with:
#!/bin/csh -f
where -f means fast.

The .login file is executed once per login session at an interactive terminal, *after* .cshrc, which I always find illogical.

Environment variables are inherited from parent shells but aliases are not, so...

you should initialise terminal control characters, prompts, default file access and maybe some environment variables in your .login file but aliases should be initialised in .cshrc.

You might like to set your prompt so that it contains useful information such as the current directory, or history number, or username (if you use different ones), or hostname (if you use different ones).

Try "man csh" and "man tcsh" for more information.

If you are working in an X oriented environment, you may have a file that is executed once for every session and not per login. This may be called .xsession (or something similar) but this is not standardised between different flavours of UNIX. There are also lots of different ways of initialising X. .xinitrc is another one.
