  • If your contact information was entered when your user account was created (it gets added to /etc/passwd) then this gets that info and creates a QR code for you automatically

    getent passwd $(whoami) | echo "$(perl -ne '/^([^:]+):[^:]+:[^:]+:[^:]+:([^ ]+) ?([^,]+)?,([^,]*),([^,]*),([^:,]*),?([^:,]*)/ and printf "MECARD:N:$3,$2;ADR:$5;TEL:$4;TEL:$6;EMAIL:$1@"')$HOSTNAME;;" | qrencode -o myqr.png

What Others Think

The default size is 135x135 pixels. Use the '-s' switch to change the size. Example, to generate a 170x170 size of image, add "-s 6"

Nowadays, more and more services from one company are outsourced to other companies in order to save time and labor. Especially when we look at companies in the IT industry, these horses are more common. This is because IT professionals are becoming less common in a world in which more skills are required of IT professionals from horses. When it comes to outsourcing, emergency departments are a whole host of terms, some of which may be more familiar to you than others, such as nearshoring-diensten. Nonarshoring is a term that has been around for a while, but not yet known to everyone. Emergency departments are, of course, different countries to which you can outsource services. Ukraine, for example. The main advantage of this way of working is sewing, so that it becomes possible during the growth process. When someone wants their business to grow, they need people, and non -orshoring can organize them. The advantage that can be seen over maritime services is that the land is closer than with offshoring, and therefore there is no time difference, for example, which might be the case with offshoring. Thus, in general, there are a number of advantages to using nonorshoring. [url][/url]

I think this is a good idea and a useful new feature. Although it will take time for people to start actively using it. When the team of the site created one project for our business, we used QR solutions for the list of our services, which could be easily found
