What Do You Want? We can’t do everything, but I’d like to address any issues you have. What’s happening in your current job or in the job you’re looking forward to?

What is the core of Linux Operating System? – Shell – Kernel – Command – Script – Terminal (Kernel)

What did Linus Torvalds create? – Fedora – Slackware – Debian – Gentoo – Linux (Linux)

Linux was initially developed for Intel X86 architecture but has been ported to other hardware platforms. (Agree)

Is it legal to edit the Linux kernel? (Yes, it ‘s under the General Public License)

What is the basic difference between UNIX and Linux Operating System? (UNIX is not Free and Open Source Software, Linux is.)

Choose the odd one out. – HP-UX – AIX – OSX – Slackware – Solaris (Slackware is a Linux version. The others are individually developed company UNIX variants.)

Linux is which kind of operating system? – Multi User – Multi Tasking – Multi Process – All of the above – None of the above (All of the above.)

The syntax of Linux commands is: – command [options] [arguments] – command options [arguments] – command [ options] arguments – command options arguments ( Command [options] [ arguments] )

Chose the odd one out. – vi – vim – cd – nano (cd is not an editor, it’s for changing a directory.)

What’s the difference between telnet and ssh? – Both are used to communicate and control remote systems – ssh encrypts transmissions, but telnet uses plain text so it is less secure.

How do you copy a file using ssh? Secure CopY scp /path/to/remote_directory

Is it possible to pass input to ssh from a local file? very much like local execution ssh < local_file.txt
