A. Study and understand each entry in the ".cshrc" and ".tcshrc" (if applicable) under your UNIX home directory on NPU's Sun workstation systems
B. COPY /cs385/.cshrc.base as your template and refer sample files ".cshrc.sample" and ".tcshrc.sample" under /cs385 on NPU48 (ONLY on NPU48!)
C. Polish your VI editing skill, make sure you are comfortable with cursor movement and vi commands
D. Create a duplicate of your current ".cshrc" file; Open 2nd connection to NPU48; edit ".cshrc" with VI:
i. Clean up unwanted and obsoleted entries such as lpath, extra aliases and comment-out lines
ii. Correct environment variables as appropriate, in particular, PATH, MANPATH, most importatnt function keys such as ERASE, INTERRUPT, STOP, SUSPEND, EOF and KILL; creat your favoriate aliases; add variable such as tabs, umask, filec, tty, noclobber, and history et al. set your prompt so it will display (minimum the following) your login-name, hostname (system name) and current working directory.
iii. Save your changes; execute command "source ~/.cshrc" or equivalent(.) in other shell to configure the file
iv. if no error after execution, you are ok; otherwise, repeate steps i through iii until no error
v. customize your .bash_profile in a way similar to above for .cshrc
E. Turn in a hard copy of your customzied ".cshrc" and ".bash_profile" file plus a soft copy to NPU48:/cs385/hmwk/hmwk-1 with a unique name such as "your-unix-login-name.cshrc" and "your-unix-login-name.bash_profile"
F. These who copy AND allow-others-to-copy their homework will get NULL for sure.
