title: how can I override alias set in .bash_aliases
body: <p>I like to use bash aliases to customize bash commands. Is there a way to override the bash alias settings, or should I rename the aliases to something different than the original command.</p>
  
  <p>eg: my .bash_aliases includes</p>
  
  <pre><code>alias ls='ls -ltr'
  </code></pre>
  
  <p>If I want to only retrieve the file name, do I need to rename the alias to something other than 'ls'? Or is there another way?</p>
