The od command in Linux is used to dump files in octal and other formats, including hexadecimal, decimal, and ASCII. This can be handy when you need to view files that aren’t ordinarily human readable, such as a binary file that’s already been compiled. But it can also prove useful in a slew of other, admittedly niche, scenarios.

tar command in Linux with examples
The tar command creates the tar file type is used to combine multiple files into a single archive. Tar actually means “tape archive,” because tar’s original purpose was to be used on tape backups – that should tell you how old this format is.

ssh command in Linux with examples
The ssh command in Linux is used to manage remote systems. Ordinarily, this would be another Linux system, but it could also be a firewall, router, or even a different operating system entirely. Using the ssh command to remotely log into another system will give you a command line terminal that you can fully access as if you were physically in front of the machine.

uname command in Linux with examples
The uname command in Linux is one of the frequently used commands. On Linux systems, there are a multitude of commands that can be used to print system information. We cover many of these commands in our guide about getting to know the hardware of your Linux box. One such command would be uname, which is especially good for listing information about the operating system itself and the Linux kernel that is running.
yes command in Linux with examples
The yes command in Linux will automatically output a “y” or any string you specify, repeatedly. It’s one of the simplest commands on Linux, and one that most users will find they never have much use for. But then when you do need it, you’ll be thankful that your Linux system already includes this Linux command by default.
Cat command in Linux with examples
