It works for sure, because somewhere i use it too.
I was meaning about the comcept:
because if you get use of this approach, when you go to work on a
machine that doesn't have this alias, immagine what you coul do if you
write rm /etc/apache/* because you are sure (or you don't pay
attention) that would ask you to confirm.
Since i read that article (it was on a magazine), i try to don't use
this kind of aliases and to pay more attention on what i'm doing.
Hello,
within bash, you could use an alternate kind of aliases in order to
circumvent any reentrance problem under a different OS:
alias rm='/bin/rm -vi'
or
alias cd=builtin cd ${CDHOME}
