How to turn on warning on rm command?

Question

I recently installed Ubuntu and find that when I delete things in terminal using

rm file

there is no warning asking me to confirm the step. I did not use the -f flag. It feels vulnerable to accidental deletion in this way. I searched online and didn't find the reason for this. How can I turn on the warning?

Answer 1

Put alias rm='rm -i' in your ~/.bash_rc or rc file of your shell. Then source ~/.bash_rc.

It will start asking for confirmation and whenever you don't want this. Use one of the following

$\rm file
$command rm file

\ escapes the alias and I like \ better due to it's lesser typing

This explanation assumes that you are using bash. The name for rc file may differs based on your shell
