My Bash PS1 line

gistfile1.sh

PS1="\`if [[ \$? = "0" ]]; then echo "\\[\\033[32m\\]"; else echo "\\[\\033[31m\\]"; fi\`[\u.\h: \`if [[ `pwd|wc -c|tr -d " "` > 18 ]]; then echo "\\w"; else echo "\\w"; fi\`]\012\$\[\033[0m\] "; echo -ne "\033]0;`hostname -s`:`pwd`\007"

[<username>.<hostname>: <current directory>]
$

Also, the entire prompts color is set to green or red depending on the return value of the command you just ran.

Green = good return val
Red = error return val

Yeah I'm confused what you would use a command counter for?

@jterrace, you are right, it is a waste of space. Gone
