title: Batch Rename in Fish shell
body: <p>I get 15 or 20 files every week with random names that include several symbols such as <code>!</code>,<code>'</code> etc. Plus there is <code>space</code>. So I need to replace <code>space</code> with <code>_</code>, and any other symbols to nothing before I can pass them to another script. I use <code>thunar</code> for the job now, but I'll very much like to automate it in the script. I'm using <code>fish</code> shell.</p>
