whats the plot

i never really used this until i ran into this article by accident, but it's fairly cool...

so:

 
echo {one,two}.sh

outputs:

one.sh two.sh

this means that you can, as the article says, do something like this:

cp /etc/apache2/httpd.conf{,.bak}

to backup your apache conf. cool huh? the article has more details and such, but that's just a summary.
