Hello, I would to be able to cancel a script I've written if I run it as root. I know there is a command "whoami" to know who is running the script, but first, I would like the script : "Be careful, you are running it as root" "please, switch to user xxxx, and rerun it. "Do you want to abort that script, or else, to run it " as root". you can see the idea; I've tried with : echo "blablalaalaal" whoami echo "blbalalblbala" but I can't put the result of "whoami" in the text displayed. the result is always written on the next line, like : blbablablaa john blbambamabma instead of : blabambamaba john blabalabmambaba I've tried with : echo "bbalbalbaba" && whoami but the result is always on two lines. Another try I made was : whoami = whoami echo "blabalababama &whoami balbabababamabab" It's not a big deal, but I like cosmetic stuff like those when I write a script. Thanks. Francois --
