This quick post gives info on checking and updating Jekyll to the latest version.

First things first, I needed to update my virtual machine’s OS. It is running CentOS 6.

For CentOS 6 updates

sudo yum update

(updates packages and keeps obsolete packages, upgrade will remove obsolete packages)

Then reboot and make a snapshot or backup of the system.

Afterwards, check the version of Jekyll or just look at the installed Gems and their version.

jekyll --version

Use the following to see what gems are installed, the current installed version and the latest version available.

gem obsolete

It is always a good idea to make a backup of your system and files before doing upgrades just in case.

Then, to update all the gem packages use:

sudo gem update

For more info on using gem and its subcommands:

gem help commands

You can also get a list of all the gems install on your system:
