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.

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?

I downloaded
http://stedolan.github.io/jq/
Linux 64 bit copy
and ftp to AIX server 64 bit.
$ chmod 777 jq
$ ./jq
ksh: ./jq: cannot execute
Does any one know what the problem is ?
I will be compiling the source files,
as Linux 64-bit binary is for the x86_64/amd64 architecture, while there's a significant chance that AIX system might be a POWER architecture .

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 just uninstalled a program (ros) from my computer (ubuntu) using the ubuntu software center.
However, since this moment, whenever I open a shell, I get the following message:
bash: /opt/ros/groovy/setup.bash: No such file or directory
Did I do anything wrong?
Have a look at ~/.bash_profile
