Linux CP Making a Backup of a file with a user defined suffix

I use this handy command so often that I’d forgotten to make a note of it here for everyone.

If you want to make a copy of a file with the same filename and a predetermined suffix of your choice then run this command replaceing the YYYYMMDD date with anything you want:

cp haproxy.cfg{,.20170209}

The above command copies haproxy.cfg into a file called haproxy.cfg.20170209
Anything after the comma can be changed as you wish.

Google+ For the Win!

Last month Google+ introduced Collections https://plus.google.com/collections/welcome
A devilishly simple way to group your posts by topic.

When you create a Collection you set the audience, so you can have private collections for posts on a topic to share with a particular audience, or you can have public collections that anyone can follow.

This is a brilliant move on Google’s part. Users can follow topic from a user, rather than every little thing they posts. It’s so simple to share with a collection too, so it’s a win for those posting the content.

Another win is that posts by content are so reader friendly that the take up on followers is very good.

Google+ is becoming my favourite place to post stuff to now, and a great place for a Global community instead of just posting stuff amongst your friends and family. The Internet is the world, not just the people you already know.

I hope more and more of you come round to Google+, and if you don’t, well you’ll be missing out but you won’t be missed, there’s a whole world of people out there.

Following this video guide and the step up booster converter from ebay below I’m going to make a Sonos Play:1 battery powered so I can enjoy some lovely music on the balcony over the summer.
