Hi,
I try set an alias under bash, something like
alias del '/bin/mv \!* /tmp/ '
but under bash, the alias (alias del='/bin/mv $* /tmp/')
always complain that tmp foler cann't be overwritten.
I sewarched nline but in vain. Could anyone give me a pointer?
I would appreciate you may reply to my email account as well.
Thanks!

It can't be access though alias.
alias give the var at the end of your alias, so
del test1 will be translate to :/bin/mv /tmp/ test1
Obviously you will get wrong message!
Solution is using function:
del() { /bin/mv $* /tmp }
add upper line in your .bashrc
Done
