a few words to the wise...

1: Despite being the same length and equally pronouncable, "ls" and "rm" are NOT synonyms for the same command.

2: NEVER type "rm /usr/bin/*" with root privileges.  EVER.

that is all.  i have a long night ahead of me.

>>10 you could learn some regex. the magic of ls -F and ` marks.

my advice for >>1 is to alias rm='rm -i' in your ~/.bashrc
