Prevent Some Commands from Running in Bash

Bash loads these files when start and exit:

• All users:
• Start up file: /etc/profile (TTY only)
• Start up file: /etc/bashrc (TTY & PTY, CentOS)
• Start up file: /etc/bash.bashrc (TTY & PTY, Ubuntu)
• Exit file:     /etc/bash.bash_logout (TTY only)
• Specific user:
• Start up file: ~/.bash_profile (TTY only)
• Start up file: ~/.bashrc (TTY & PTY, All Linuxes)
• Exit file:     ~/.bash_logout (TTY only)

To prevent some commands from running, for example "sudo rm", add a function similar to this to the a start up  file:

function sudo {
  if [[ $1 == "rm" ]]; then
    echo "Command not allowed: sudo rm";
  else
    #the doublequotes are important to run
    #commands with quotes/doublequotes
    command sudo "$@";
  fi

}
