UNIX Terminal – a kind of illness that affects both Mac/Hackintosh & Linux users. (Experts agree that with MS Windows people it is generally known as DOSitis.) In the latter stages and severest forms of this affliction, there is no known cure.
Symptoms include up to 23 hours a day facing a square box or flat panel which emits light of various intensities and colours. Meals are taken without moving from this device, and the food is eaten with one hand while the other one furiously and/or slowly taps away at small square blocks on something called a 'keyboard'.
Other side effects include completely ignoring wife/girlfriend/children/cat/dog, and breaking off all personal and visual contact with friends and family, apart from sending messages to them electronically via this machine.
The affected person can be observed staring intently at a small black 'window' on the screen which contains only lines of white lines of text which say weird things like [PCI config begin] or [root@linux] $. These lines are usually static but occasionally burst into life with scores and hundreds of lines whizzing past. Far-gone patients even claim to understand what most of it means!!
It has even been known for these poor lost souls to expand the size of the black window to half the size or even the full area of the screen, which thus completely obliterates and blocks out the view of all colours, pictures, icons, text, information and other interesting (and also useful one might say) things on their monitors. This is the time to call for the men in the white coats with the van to bring a straitjacket and take this demented person away and lock them in a padded cell (with no computer!), throw away the key and leave them there for ever.
Apologies to anyone who really is (or has a loved one who is) suffering from some serious illness or life-threatening disease. The above is meant to cheer you up, not insult you, demean you or bring you down.
