Hello Everyone, I am a new one on this site. I just want to know the most important questions of Linux. My interview has been scheduled for next to next week. If anyone helps me please suggest some tricks and tips. I have already prepared to some topics like basic components of Linux, BASH and DOS, daemons, swap space in Linux and some more.
Already passed: Oracle Cloud, AZ-900
Taking AZ-104 in December.

Might be he is asking for Linux Administration Jobs, Here I am listing a few questions through you can make preparation for Linux Interview Questions:
here I am sharing with you some basic Linux command:
dir command works like Linux is command, it lists the contents of a directory.
Free command shows the system memory usage (free, used, swapped, cached, etc.) in the system including swap space. Use the
-hoption to display output in human friendly format.
grep Command searches for a specified pattern in a file (or files) and displays in output lines containing that pattern as follows.
groups command displays all the names of groups a user is a part of like this.
Gzip helps to compress a file, replaces it with one having a
.gzextension as shown below:
gunzip expands or restores files compressed with gzip command like this.
head command is used to show first lines (10 lines by default) of the specified file or stdin to the screen:
history command is used to show previously used commands or to get info about command executed by a user.
hostname command is used to print or set system hostname in Linux.
hostnamectl command controls the system hostname under systemd. It is used to print or modify the system hostname and any related settings:
hwclock is a tool for managing the system hardware clock; read or set the hardware clock (RTC).
hwinfo is used to probe for the hardware present in a Linux system like this.
id command shows user and group information for the current user or specified username as shown below.
ifconfig command is used to configure a Linux systems network interfaces. It is used to configure, view and control network interfaces.
ionice command is used to set or view process I/O scheduling class and priority of the specified process.
If invoked without any options, it will query the current I/O scheduling class and priority for that process:
iostat is used to show CPU and input/output statistics for devices and partitions. It produces useful reports for updating system configurations to help balance the input/output load between physical disks.
ip command is used to display or manage routing, devices, policy routing and tunnels. It also works as a replacement for well known ifconfig command.
This command will assign an IP address to a specific interface (eth1 in this case).
iptables is a terminal based firewall for managing incoming and outgoing traffic via a set of configurable table rules.
The command below is used to check existing rules on a system (using it may require root privileges).
