Re: 12.04 LTS, Toshiba Satellite L850, RTL8111/RTL8168 WiFi non existent.
Not at all. I enjoy what I do and I couldn't do it if there weren't questions.
I hope I don't drive you nuts;
Nothing relevant or even mildly alarming there.

In the context of Linux/Unix, pipe or | means approximately to pipe the first command through the second command. In other words, run this command and use its output in the second command. If we asked for all the kernel messages with:...then we'd get 100 to 200 lines. But suppose we only want lines related to 'rtl'. We'd type:Now, we'd see maybe ten lines and all would include rtl. Much more informative and easier to understand.
On a side note... can you explain "pipe," simply? Wikipedia's explanation is too dense for me.
Now, I assume that moving and renaming files using the CLI is, really, the same as if I did it using the GUI, right?
Almost; in this context "accessed" really means "created or modified." So if you created a file last week called chili.txt and then changed it in some way today, the "accessed" date would change accordingly. For educational purposes, see the CLI version:
In the file properties can I mentally substitute the word "created" for "accessed?"
ls -lct /etc/modprobe.d
It means the Realtek card reader driver is from the staging directory. When drivers are in the late stages of development, they are added to the kernel as 'staging.' They are staged to become mainstream but may contain a bug or two; not that all drivers may or may not contain a bug! This is just saying that the driver is almost ready but may have a wart or two; you have been warned. Again for information purposes, see:If your card reader is working as expected, you may safely ignore the warning. If not, you are invited to file a bug report.
What IS the meaning of the rts5139 line?
As long as the hardware is working, I suspect you will have wireless. If the hardware takes Tuesday off as a sick day, you will not have wireless.
Restarting now.... and we still have wireless. Good.
I look forward to your re-seating experiment. Dr. Chili advises all users to fiddle with the screwdriver with care and the manual at hand.
