Sharing My Prompt

[Roger]

Just wanted to share my current prompt after a month or so polishing.

Seems to be pretty darn good and figure I'll probably use this one for a good
long time.  (Yea right. ;-)

PROMPT_COMMAND='RET=$?; if [[ $RET -eq 0 ]]; then echo -ne 
"\n\033[0;32m$RET\033[0m ;-)"; else echo -ne "\033[0;31m$RET\033[0m :-(\n"; fi; 
echo -ne "\n"'
PS1='\[\033[01;32m\]\u@\h\[\033[01;34m\] \w \$\[\033[00m\] '


Gives the following return value (w/ smiley) separated by a few blank lines.
(Ref. ArchLinux Wiki, but mine is better by adding a few additional newlines!)

roger@localhost2 ~ $ echo


0 ;-)
roger@localhost2 ~ $ echl
bash: echl: command not found

127 :-(
roger@localhost2 ~ $ 



I've also just incorporated the following PS4 value for shopt xtrace:
PS4="$0 line ${LINENO}: "

Output modifies xtrace stdout adding script name & line numbers.  Wow, much
more informative then the default xtrace stdout! (Ref. Oreilly's
