If your Linux can not use apt-get or apt

Recently, I ran into a problem. 

I tried to install gcc on a Linux.

And I tried to use apt-get and apt. But they are not there. And I tried to install apt-get and apt. I could not find the command.

So, I tried the following:

sudo yum -y install gcc gcc-c++ numpy python-devel scipy

And it works. 

 

And I tried 'perl', 'java'. All worked. 

 

sudo yum -y install gcc gcc-c++ numpy python-devel scipy perl java

sudo yum -y install java-1.6.0-openjdk-devel, after install this, then you can use javac, java to run java class.

 

And further, if you use mac, and your  linux there  does not have the apt-get, etc, you can use brew:

http://brew.sh/

it is quite helpful.
