Interactive remove is very useful option.

Even that rm command was not constructed to remove directories by default you can force rm to remove directory and all files in inside by -fr option combination. Be very careful with this command it can do lots of damage: 

rm -fr dir/

rm - force remove files and directories

Sometimes you need to make rm command to do not accept any other options. Lets assume that we have a file called "-i" and we need to remove it. In this case we nee to use "--" options wich will instruct rm command to not accept any other options. 

rm -- -i
rm - do not accept more options
Or we might need to remove filename which starts with meta character. In this case we need to escape this meta character with "\". For example to remove $rm file we issue command: 
rm \$rm
rm files with meta characters
