I'm trying to find a zsh guide and I notice the guide on the official website hasn't been updated for over a decade. So I'd like to know if there are anything in that guide has been changed and should be skipped when reading, and how many new things has been added during these years. Or are there any more recent guides that I can read instead of the official one?

The official guide probably is outdated.
I would advise you to use the man command. In this case man zsh and the consult the following hyper-links:
Linux Zsh Man Page
The Zsh Wiki

I just want to use my computer from the terminal. I have read through the Apple Terminal Help documentation, but am looking for more instruction.
i found this 2003 pdf doc. it is pretty comprehensive and still relevant to this day. i suggest setting up a developer account if you are keen to learn more.
As for the things you intend to do on terminal,
man is your great dictionary assistant
cd, ls and pwd are your great buddies in navigating around the files and folders
curl is your great bestie for browsing web pages
.bash_profile is where your configuration lies
Hope this helps!

I know that Xcode downloads a lot of developer documentation for everything from Objective-C to Swift on to your mac hard drive if you choose to download the developer documentation.
I've navigated to the directory before, but I didn't note down its location, and now I am having trouble finding it. It had PDF versions of a lot of documentation which is available on the Apple website.
Any idea what the location is ? This question is posted on stackoverflow.com, because the people who will know the answer are programmers who visit this site, as opposed to superuser.
EDIT: Applications/Xcode/Contents/Developer/Documentation/DocSets/com.apple.adc.documentation.docset is not what I am looking for. While it has some documentation, it is not the treasure trove that contains documentation on Objective-C, Swift, Memory management and much much more....that is all stored in some other location... how to find it ?
It is found here:
~/Library/Developer/Shared/Documentation/DocSets/com.apple.adc.documentation.docset/Contents/Resources/Documents/documentation

like other languages?
I googled it and came up with
https://www.google.com/?gws_rd=ssl#q=bash+specification
which did not list any specifications, just manuals and guides.
Thanks,
IEEE 1003.1 (“POSIX”) defines a standard “Shell Command Language”. You can find the 2016 edition here.
GNU Bash is an implementation of that language, with many extensions. The only specifications for the extended bash language are the bash reference manual and the bash source code.
I would consider the manual to be the spec. Bash Manual

Is there a Java library/API available to interact with Windows OS, like executing commands on the command prompt and returning the output back to the program?
You can use java.lang.Runtime.exec() to do it, but read this first.
Use the ProcessBuilder, which is available starting from Java 1.5!
It has the nice ability to let you redirect the error stream which makes you only have to cope with one InputStream to read from.
Good article here: Runtime.exec() and the API is here: link text

I've spent some time today looking for a pure ruby library that will parse an excel workbook. I could find the parseexcel gem in the repos, but the problem is that I can't find any documentation on it. and the rdoc is pitiful. so, my question is 1) is there good documentation out there for this gem? 2) if not, is there another gem that does the same thing that has good documentation?
thx :)

Roo is a good alternative with documentation.
