[Ubuntu-BD] Problem regarding netbeans

[tanjir]

Very good question. We often tell users to run commands, but I guess most times users don't really know what they mean.
So, in the proposed solution, you were asked to run these two commands:
1. sudo chmod 755 netbeans-6.7.sh
sudo: this command is used before other commands. For example, here, "chmod 755 something.sh" is a command by itself. But the command runs as current user. If you add sudo before this command, it will run as root user. Just for fun create a file called foo.txt. And copy like following "sudo cp foo.txt bar.txt" (It simply copies foo.txt file to bar.txt). Then type "ls -al" (it lists all the files and related information). You will see the owner of bar.txt is root. Now you can't remove bar.txt by "rm bar.txt", you have to use "sudo rm bar.txt". Once you remove try the same cp command without sudo (e.g. cp foo.txt bar.txt) and do "ls -al" and see the owner now is you.
chmod: stands for change mode of the file. Using chmod you can modify the file permission. By default in ubuntu, files don't have executable permission, so here you ar adding executable permission. To know more about chmod, read this article: http://ss64.com/bash/chmod.html
2. sudo ./netbeans-6.7.sh
You can run ./netbeans-6.7.sh as well. Usually that is what you will do most of the times. But this case, as you are installing a software, and it requires to access some files and directories which are owned by root, you are told to add sudo before the command. ./executable.sh is same as running any .exe file in DOS. The difference is, you can not only run .sh but also few other extensions (.pl, .tcl and so on) with proper headings.
(one warning for this type of execution: for example you have exec.sh file inside foo directory. So you can run a) "./foo/exec.sh" or b) "cd foo" and "./exec.sh". Both looks innocent and same; but they are not. In the case a your current directory is one level up. So if your .sh file needs any resource inside foo directory, it won't be able to find them. The proper command will be case b.)
