unalias

Recomenda-se que o comando rm principalmente de usuários poderosos como root, sejam transformados em algo do tipo rm -i. Desta forma, a cada arquivo que se desejar remover, o sistema solicitará a confirmação.

É claro, que para um grande número de arquivos, isto passa a ser mais um aborrecimento do que uma medida de precaução. Nestas situações, para utilizar o comando sem a conversão imposta pelo alias, basta precedê-lo pelo caractere \.

Veja só:

# rm *
rm: remove a? s
rm: remove? n
rm: remove 00index.txt? s
 ...

Quando o número de arquivos for grande e você tiver certeza do que está fazendo:

# \rm *

Concluindo, deixe o comando rm do usuário root com um alias
para rm -i. Quando precisar fazer deleções em massa, utilize \
para evitar a conversão apenas naquele momento.
