ls List files and directories in the current directory

ls -l List in long format with extra details

ls -a List all files, including hidden ones

Creating directories is straightforward with the mkdir command:

mkdir newFolder Create a new folder 'newFolder'

mkdir .NewFolder Create a hidden directory (useful for configuration files)

mkdir A B C D Create multiple directories simultaneously

mkdir /home/user/Mydirectory Create a directory in a specific location

mkdir -p A/B/C/D Create nested directories

File manipulation commands

cat -n filename View the content of a file and display line numbers

chmod 700 filename Change the access permissions of files to make them readable, writable, and executable by the owner only

history | tail -n 10 Check the last 10 commands you have run

rm -r directory_name Remove a directory and all its contents

echo -e "Apple\nMango\nBanana\nCherry\nKiwi\nOrange\nGuava" > fruits.txt cat fruits.txt Create a .txt file, add content (one fruit per line), and display the content

I’ve just started my journey, and today was all about understanding the Linux kernel architecture and mastering some basic Linux commands. Here are a few commands I practiced:

• ls: Lists directory contents

• cd: Changes the current directory

• pwd: Displays the current directory path

• cp: Copies files or directories

• mv: Moves or renames files or directories

• rm: Removes files or directories

• touch: Creates an empty file

• mkdir: Creates a new directory

• echo: Prints content in files

• sudo useradd: Adds a new user

• sudo userdel: Deletes a user

Feeling more empowered already! Looking forward to learning more and growing in this field. 💻🌐
I will share weekly posts with you about my journey.
