Sudo
This
SuperUserDo is the most important command Linux newbies will use. Every single
command that needs root's
permission, need this sudo command. You can
use sudo before each command that requires root permissions.
ls - list
Just like the other, you often want
to see anything in your directory. With list command, the terminal will show
you all the files and folders of the directory that you're working
in. Let's say I'm in the /home folder and I want to see the directories &
files in /home.
Cd
Changing directory (cd) is the main
command that always be in use in terminal. It's one of the most Linux
basic commands. Using this is easy. Just type the name of the folder you
want to go in from your current directory. If you want to go up just do it by
giving double dots (..) as the parameter.
Let's say I'm in /home directory
and I want to move in usr directory which is always in the /home.
Here is how I can use cd commands.
mkdir
Just changing directory is still
incomplete. Sometimes you want to create a new folder or subfolder. You can
use mkdir command to do that. Just give your folder name
after mkdir command in your terminal.
cp
Copy-and-paste is the
important task we need to do to organize our files. Using cp will
help you to copy-and-paste the file from terminal. First, you determine the
file you want to copy and type the destination location to paste the file.
rm
rm is
a command to remove your file or even your directory. You can use -f if the
file need root permission to be removed. And also you can use -r to
do recursive removal to remove your folder.
apt-get
This command differs
distro-by-distro. In Debian based Linux distributions, to install, remove and
upgrade any package we've Advanced Packaging Tool (APT)
package manager. The apt-get command will help you installing the software you
need to run in your Linux. It is a powerful command-line tool which can perform
installation, upgrade, and even removing your software.
In other distributions, such as
Fedora, Centos there are different package managers. Fedora used to have yum but
now it has dnf.
grep
You need to find a file but you don't
remember its exact location or the path. grep will help you to solve
this problem. You can use the grep command to help finding the file
based on given keywords.
cat
As a user, you often need to view
some of text or code from your script. Again, one of the Linux basic commands is cat command.
It will show you the text inside your file.
poweroff
And the last one is poweroff.
Sometimes you need to poweroff directly from your terminal.
This command will do the task. Don't forget to add sudo at the beginning of the
command since it needs root permission to execute poweroff.
