‘Tool(s) “patch” is(are) missed, please install it(them)’ when Trying to Patch Magento

If you receive a notification in your Magento back office alerting you to install a critical patch (like below)…

…and you end up Googling how to do so and come across guides (like ours) which instruct you to patch over the command line (SSH), the first time you try this, you may receive the following error:-

Tool(s) "patch" is(are) missed, please install it(them).

All this means is that the tool ‘patch’ is not installed so subsequently, the command ‘patch’ that your bash script contains is not recognised.

All you need to do is simply install patch using the below:-

sudo yum install patch

This should be all that is required but if you run into any issues, please leave a comment below with details and we’ll see if we can help you out.
