Hello everyone. This is Syeda. I am very much interested to work in Cyber security world. So I am taking courses at St. Philips. Part of that I am currently on the Linux course. Everything is so new to me in Linux. I would be much obliged if you can give me some information about how to find the system configuration info in Linux. Is it the same way for each distribution? One more question, why we have so many distributions? Can't we just have one best for each category? Thank you all in advance.
What kind of configuration are you asking for? Following commands maybe help more /proc/cpuinfo dmidecode | more lspci lsusb lsb_release -a Use Internet search engines with Code: why we have so many distributions? While you are at it, also find out why there are so many makes of cars. Why not just one lorry, one family car, one ambhibious car?
Because we can! It is open source and everyone can make his own. Obviously, this has pros and cons. Usually, the configuration of system wide settings are stored in the /etc folder. These are text files which can be read and edited by and editor (and easily saved/restored/version controlled). Each program has its own configuration file. Bigger programs have several of them stored in folders. For example, your network configuration is (depending on distribution) in /etc/network/interfaces In addition to the commands @Taleman already posted, there is also "dmesg" (diagnostic message) you could have a look at: https://www.howtoforge.com/linux-dmesg-command/
I am new to Linux so I have so many questions regarding the most basic commands such as Cd and the characters. I guess my question is do you have any advise to master the most fundamental commands? Obliviously, practice is the short answers, but I would like to know if you have an specific website or reading material that simplify the commands. Thanks,
