I have noticed in all my Ubuntu servers the alias rm -i is ignored when you run sudo rm * as root. Is there something in sudo that is causing this behavior? I know you don't need to use sudo when you are root however in the event that a Jr SA were to do so it would remove the contents of the directory. Also knowing that rm in Ubuntu does not preserve / it could mean a total system meltdown.
Example as root:
johndoe@hostname:/tmp/foobar $ sudo su -
root@www3d:~# cd /tmp/foobar
root@hostname:/tmp/foobar# for i in 'a b c d e f g' ; do touch $i ; done
root@hostname:/tmp/foobar# sudo rm *
root@hostname:/tmp/foobar# for i in 'a b c d e f g' ; do touch $i ; done
root@hostname:/tmp/foobar# rm *
rm: remove regular empty file `a'? y
rm: remove regular empty file `b'? y
rm: remove regular empty file `c'? y
rm: remove regular empty file `d'? y
rm: remove regular empty file `e'? y
rm: remove regular empty file `f'? y
rm: remove regular empty file `g'? y
root@hostname:/tmp/foobar# for i in 'a b c' ; do touch $i ; done
root@hostname:/tmp/foobar# rm *
rm: remove regular empty file `a'? y
rm: remove regular empty file `b'? y
rm: remove regular empty file `c'? y
root@hostname:/tmp/foobar# for i in 'a b c' ; do touch $i ; done
root@hostname:/tmp/foobar# sudo rm *
root@hostname:/tmp/foobar# ls
root@hostname:/tmp/foobar# exit
logout
Example as user:
johndoe@hostname:/tmp/foobar $ for i in 'a b c' ; do touch $i ; done
johndoe@hostname:/tmp/foobar $ rm *
rm: remove regular empty file `a'? y
rm: remove regular empty file `b'? y
rm: remove regular empty file `c'? y
johndoe@hostname:/tmp/foobar $ for i in 'a b c' ; do touch $i ; done
johndoe@hostname:/tmp/foobar $ sudo rm *
rm: remove regular empty file `a'? y
rm: remove regular empty file `b'? y
rm: remove regular empty file `c'? y
