=== Craft a command to delete all files in /boot for kernels that don't matter to you using brace expansion to keep you sane. Remember to exclude the current and two newest kernel images. From above Example, it's ===
<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">sudo rm -rf /boot/*-3.19.0-{25,56,58,59,61,65}-*</div>

<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">sudo apt-get -f install</div>

<div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">sudo apt-get autoremove</div> <div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">sudo update-grub</div> <div style="background:#eee;border:1px solid #ccc;padding:5px 10px;">sudo apt-get update</div>
