ok some of ye might of seen this be4 but for those who haven't it seperates the nubs from the pros

so here it is:


CHALLENGE
Write a shell script that prints current directory and then prints its own code

RESTRICTIONS
The solution script can use only variable assignments and the echo command and try and use the least amount of lines possible

seperates them in what way?

They're called Quines and to write one from scratch does involve a good understanding of the language 'that sort of brain'

bpmurray

EveningEcho () {
echo -e "$*"
echo "EveningEcho '$*'"
}

EveningEcho 'EveningEcho () {
echo -e "$*"
echo "EveningEcho \047$*\047"
}'

That prints the file itself. I don't get the print the directory stuff - was this supposed to do that too? (apropos the use of EveningEcho, yes, I'm originally from down there). If you want tee directory list, just add echo * as the first line, and after the first '.
