I would like to split a huge text file into separate text files. I use:
split -l 1000 file.txt split_file
and I will get split_fileaa, split_filebb, etc.
How can I change the extension to be
split_file0.txt, split_file1.txt, etc?

--additional-suffix is what you need for the additional suffix :
split -l 1000 -d --additional-suffix=.txt file.txt split_file

There is a -d option for numeric suffixes.

How can I find out how many CPU cores is a job running on a Linux system using?
Is it somehow through the top command?
you can use ps -aF or I am guessing you are referring to htop which is a graphical tool.

I need to find the location of an existing csr file on my linux server, but I'm not sure where it's stored.
What's the best way to find this out?
If you have locate installed (it is part of GNU Findutils, may be included in your installation) then you can simply do:
locate myfile.csr
Otherwise you may have to search the whole filesystem with find:
find / -name "myfile.csr"
If you have some idea of where it might be (eg under a certain home dir or something) then you can specify that directory in place of the /.

I read in "TCP/IP Network Administration" by O'Reilly, 2002, that typing the route -n command should bring up a routing table.
When I typed it into the terminal on a Mac, it returned the following:
usage: route [-dnqtv] command [[modifiers] args]
What is the correct command to use to see the routing table in my terminal?
On Mac OS X you can use netstat(1). In your case, netstat -nr, probably.

Here is the scenario,
I have 1000 files in a folder each 0f 3 MB, I want to zip all files into 50MB each zip and remove those files
50MB may contain 20 files or 10 files but that zip package should be <=50MB
Do they have to be separate, complete zips, or do you just want each file to be <50mb. If so, look at adding -s 50M to your zip invocation (check man zip for split)
