Hello,
Removing files is not worth doing.
The victim will immediately find what happened and will recover his
files
and then will consider what made the trouble.
I don't say (. /bin) is safe in untrusted environment.
Someone might steal my private info using some trick.
Security is tradeoff with convenience.
I guess we (member of 9fans) are happy enough working in trusted
environment.
