Despite using Linux as working environment for last couple of years, there are time when I forget some commands, specially at the time of needs. I have to gogole them to refresh my memories. Some of those commands may not be used frequently and some even once in a period. Remembering them when you are not system admin is tough task, and I have found it particular hard as I tend to forget them even more often.
If you are thinking to switch to Linux platform or already had but you have been told you would need to know some level of console commands. Don’t worry there are so many guides in web that can make you expert in 24 hrs. Don’t hold back to use Linux just because you don’t know some commands. Learn it, practice it. The ability to execute series of vast, simple or complex commands to perform certain operations is what makes it better than other OS.
Last time we learned how to install jdk and glassfish with apt-get install commands. Today let’s try to install these manually. Both method have it’s own advantages but I usually perform manual operation.
To install JDK, IDE and Glassfish server at Linux platform is different from than that at Window. Any programmer who is willing to switch working platform may face problem on how to do that? But relax, it’s not that hard.
I/O operation is important part in programming. Many time we have to read from file or files. Sometime we have to write down information or error message when executing program
My first question for the peoples -“What do you think hackers are?”
Software is developed by team of programmer and most of software life period goes for maintenance and support. Code convention increases readability and efficiency of software.
