Automatic capitalization when typing terminal commands
Well I found the solution with help from @Allen. I tried restarting my computer in Safe Mode. The problem with capitalization went away. Based on this result it was probably due to something I loaded onto my machine. While I was in Safe Mode I started by looking at the Startup items found in the System Preferences/User and Groups. I hadn't carefully checked the Login Items in quite a while and I found out I had many. Some of these were suspicious in that the kind of item was unknown. I show this in the images below:





I had several that fit that description. Using the minus symbol shown in the bottom left of the window I deleted the suspicious login items and rebooted my computer back to regular user mode. To my joy the auto capitalization was gone. I deduce it must have been connected to one of the login items I removed. Had I removed them one-at-a-time I might have beem able to determine which one was the culpit. As it is I can only narrow it down to the ones I removed. None of these were new additions so I must have changed settings in one of these to suddenly cause my troubles. Due either to old age or the fact that auto capitalization was driving me crazy, I can't recall what changes were made recently. I may go back and try to determine which specific one was causing this but that is left for a future date.
