One of the data elements produced by the finger command gives information on how long a logged in session has been idle. Where does finger get that information from on RedHat? I've looked in /proc/<pid>/ but did not find anything useful, and the documentation doesn't go into the commands implementation.
So, where in the system is finger (or w) pulling this information from?
The finger program get's this information from utmp file located at /var/run/utmp.

is it possible to see all files that are theoretically viewable by a link but not linked on the main website?
For example:
Let's say the website has:
index.html
undepage/index.html
supersecretdocument.pdf
Is it possible to see the supersecretdocument.pdf know that the document exists without knowing that it's there?
If you're asking "Can I know a file exists without trying to GET (or HEAD) it?", the answer is "no."

scenario: I have ssh onto a remote server and have created a directory named helloworld/ and after working with it for some time I wanted to rename it to something like hello_world/ I was wondering how I can easily do that.
I was looking online and I was not able to find much resources, but I think this is a pretty simple thing, so I imagine there will be a simple way of achieving this.
Please let me know
mv <source_directory> <target_directory>

Hard links cannot span physical devices. Exactly this statement I read while understanding the concept of hard link in Linux. Can anyone help me to understand this ?
A filename, is a pointer to an inode.
So if you're not on the same drive, it's impossible to link a file, because the inodes belongs to a specific disk

My mouse sensitivity sometimes changes on its own, and I would like to see what the acceleration/sensitivity values are at any point. Sometimes I forget my keyboard repeat rate settings and have to feel around for it.
Is there a command like "xset", but to get the current values?
From the man of xset :
q
The q option gives you information on the current settings.
Is that what you are looking for ?

I am new to terminal and I just wanted to know if there's any way I could start from where I left off to avoid typing the whole commands again.
Indeed there is. This is the main feature of GNU Screen, and also of tmux - choosing one is a matter of preference.
