In simple terms, a Linux command is a directive given to the operating system (OS) to perform a specific task, such as creating a file, navigating directories, or installing software. These commands are executed through the command line interface (CLI) or terminal, which allows users to interact directly with the OS. You can access the terminal by opening the terminal application or using the keyboard shortcut &#8220;Ctrl+Alt+T&#8221;.<\/p>\n\n\n\n<p>Linux commands are composed of keywords, parameters, and options. The keyword specifies the action to be performed, while the parameters provide additional information required for the command&#8217;s execution. Options, on the other hand, modify the behaviour of the command, allowing you to customise its execution according to your needs.<\/p>\n\n\n\n<p>Now that we have a basic understanding of Linux commands, let&#8217;s explore the most commonly used ones for beginners.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"basic-linux-commands-for-beginners-ls-pwd-cd-mkdir-and-more\">Basic Linux Commands for Beginners (ls, pwd, cd, mkdir, and more)<\/h2>\n\n\n\n<p>To get started with Linux, it&#8217;s crucial to familiarise yourself with some basic commands. These commands lay the foundation for your journey and help you navigate the Linux environment efficiently. Let&#8217;s explore a few essential ones:<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"536\" src=\"https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-1024x536.jpg\" alt=\"Image of Linux Ubuntu terminal\" class=\"wp-image-1649\" srcset=\"https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-1024x536.jpg 1024w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-300x157.jpg 300w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-768x402.jpg 768w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-696x364.jpg 696w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-1068x559.jpg 1068w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal-803x420.jpg 803w, https:\/\/www.mcloud9.com\/blog\/wp-content\/uploads\/2023\/07\/Image-of-Linux-Ubuntu-terminal.jpg 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>ls (List)<\/strong>: The <code>ls<\/code> command lists the contents of a directory. It provides you with a detailed view of files and directories within the current directory. By default, it displays the names of the files and folders in alphabetical order.<br><\/li>\n\n\n\n<li><strong>pwd (Print Working Directory)<\/strong>: Use the <code>pwd<\/code> command to display the current directory. It shows you the full path to your current location in the system.<br><\/li>\n\n\n\n<li><strong>cd (Change Directory)<\/strong>: The <code>cd<\/code> command enables you to change your current directory. You can navigate to a specific directory by specifying its path after the command. For example, <code>cd \/path\/to\/directory<\/code> will take you to the desired directory.<br><\/li>\n\n\n\n<li><strong>mkdir (Make Directory)<\/strong>: Need to create a directory? The <code>mkdir<\/code> command is used to make a new directory. Simply provide the desired directory name after the command, and Linux will create it for you. For example, <code>mkdir mydirectory<\/code> will create a directory named &#8220;mydirectory&#8221; in the current directory.<br><\/li>\n\n\n\n<li><strong>rm (Remove)<\/strong>: When it comes to deleting files and folders, the <code>rm<\/code> command comes in handy. However, be cautious when using this command, as it permanently removes the specified files or directories. To remove a file, use the <code>rm<\/code> command followed by the file name. To remove a directory, use the <code>rm<\/code> command with the <code>-r<\/code> option, which stands for &#8220;recursive,&#8221; to remove the directory and its contents. For example, <code>rm myfile.txt<\/code> removes the file named &#8220;myfile.txt,&#8221; while <code>rm -r mydirectory<\/code> removes the directory named &#8220;mydirectory&#8221; and its contents.<\/li>\n<\/ol>\n\n\n\n<p>These basic and frequently used Linux commands are essential for navigating and manipulating files and folders. Now, let&#8217;s move on to the 25 most-used Linux commands, providing detailed explanations for each command.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"the-25-most-used-linux-commands\">The 25 Most-Used Linux Commands<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ls-list\">ls (List)<\/h3>\n\n\n\n<p>As mentioned earlier, the <code>ls<\/code> command lists the contents of a directory.\u00a0 By default, it displays the names of the files and directories in alphabetical order. However, you can use various options with the <code>ls<\/code> command to customise its output. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ls -l<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>ls -l<\/code> displays the long format listing, providing detailed information such as file permissions, owner, size, and modification date.<br><\/li>\n\n\n\n<li><code>ls -a<\/code> shows all files and folders, including hidden files that start with a dot.<br><\/li>\n\n\n\n<li><code>ls -lh<\/code> combines the <code>-l<\/code> and <code>-h<\/code> options to display file sizes in a human-readable format.<\/li>\n<\/ul>\n\n\n\n<p>The <code>ls<\/code> command is a versatile tool for exploring the contents of directories and obtaining relevant information about files.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"pwd-print-working-directory\">pwd (Print Working Directory)<\/h3>\n\n\n\n<p>The <code>pwd<\/code> command prints the current working directory, which represents your current location within the file system. When you are navigating directories, it&#8217;s essential to know where you are in the file hierarchy. The <code>pwd<\/code> command displays the full path from the root directory to your current location. It helps you understand your context and assists in executing commands on specific files or directories.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>pwd<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"cd-change-directory\">cd (Change Directory)<\/h3>\n\n\n\n<p>The <code>cd<\/code> command is used to change your working directory. It allows you to navigate through the file system and access different directories. Here are some examples of using the <code>cd<\/code> command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>cd \/path\/to\/directory<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>cd \/path\/to\/directory<\/code> takes you to the specified directory.<br><\/li>\n\n\n\n<li><code>cd ..<\/code> moves you one level up in the directory hierarchy.<br><\/li>\n\n\n\n<li><code>cd ~<\/code> or <code>cd<\/code> (without any arguments) takes you to your home directory.<\/li>\n<\/ul>\n\n\n\n<p>Being proficient with the <code>cd<\/code> command enables you to move around the file system efficiently and access the directories you need.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"mkdir-make-directory\">mkdir (Make Directory)<\/h3>\n\n\n\n<p>Creating directories is a common task in Linux, and using the command <code>mkdir<\/code> serves this purpose. It allows you to make a new directory with a specified name. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>mkdir mydirectory<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>mkdir mydirectory<\/code> creates a directory named &#8220;mydirectory&#8221; in the current working directory.<\/li>\n<\/ul>\n\n\n\n<p>You can also create nested directories by providing the full path. If any directories in the specified path don&#8217;t exist, running the command <code>mkdir<\/code> creates them as well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"rm-remove\">rm (Remove)<\/h3>\n\n\n\n<p>The <code>rm<\/code> command is used to delete files and folders from the system. However, use this command with caution, as it permanently deletes the specified files or directories. Here are some examples of using the &#8220;rm&#8221; command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>rm myfile.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>rm myfile.txt<\/code> removes the file named &#8220;myfile.txt&#8221; from the current directory.<br><\/li>\n\n\n\n<li><code>rm -r mydirectory<\/code> removes the directory named &#8220;mydirectory&#8221; and its contents. The <code>-r<\/code> option stands for &#8220;recursive&#8221; and is necessary to delete directories.<\/li>\n<\/ul>\n\n\n\n<p>Always double-check your command before executing it with the <code>rm<\/code> command, as the deletion process cannot be undone.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"touch-create-empty-file\">touch (Create Empty File)<\/h3>\n\n\n\n<p>The <code>touch<\/code> command is used to create an empty file. It updates the access and modification timestamps of an existing file or creates a new file if it doesn&#8217;t already exist. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>touch newfile.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>touch newfile.txt<\/code> creates a new empty file named &#8220;newfile.txt&#8221; in the current directory. <\/li>\n<\/ul>\n\n\n\n<p>The <code>touch<\/code> command is also useful for updating the timestamps of files when needed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"cp-copy\">cp (Copy)<\/h3>\n\n\n\n<p>The <code>cp<\/code> command can be used to create copies of files and directories. It takes two arguments: the source file or directory you want to copy and the destination where you want to place the copy. Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>cp file.txt \/path\/to\/destination<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>cp file.txt \/path\/to\/destination<\/code> creates a copy of &#8220;file.txt&#8221; in the specified destination directory.<\/li>\n<\/ul>\n\n\n\n<p>You can also use the <code>-r<\/code> option with the <code>cp<\/code> command to recursively copy directories and their contents.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"mv-move\">mv (Move)<\/h3>\n\n\n\n<p>The <code>mv<\/code> command in Linux is used to move or rename files and folders. It is similar to the <code>cp<\/code> command but with the added functionality of removing the original file or directory after the move operation. The basic syntax of the <code>mv<\/code> command is <code>mv source destination<\/code>.\u00a0 Here are some examples of using the <code>mv<\/code> command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>mv file.txt \/path\/to\/destination<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>mv file.txt \/path\/to\/destination<\/code> moves &#8220;file.txt&#8221; to the specified destination directory.<br><\/li>\n\n\n\n<li><code>mv file.txt newname.txt<\/code> renames &#8220;file.txt&#8221; to &#8220;newname.txt&#8221; within the same directory.<\/li>\n<\/ul>\n\n\n\n<p>The <code>mv<\/code> command is a handy tool for organising and managing files and folders.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"clear-clear-the-terminal\">clear (Clear the Terminal)<\/h3>\n\n\n\n<p>The <code>clear<\/code> command clears the terminal screen, providing a fresh and clean working environment. It removes all previous commands, outputs, and scroll history, giving you a clear slate to work with. Simply typing &#8220;clear&#8221; and pressing Enter clears the terminal screen, making it easier to read new output and focus on your current tasks.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>clear<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"cat-concatenate-and-display-file-content\">cat (Concatenate and Display File Content)<\/h3>\n\n\n\n<p>The <code>cat<\/code> command is used to display the contents of a file on the terminal. It can also be used to concatenate multiple files and display their combined content. Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>cat file.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>cat file.txt<\/code> displays the content of &#8220;file.txt&#8221; on the terminal.<br><\/li>\n\n\n\n<li><code>cat file1.txt file2.txt<\/code> concatenates the contents of &#8220;file1.txt&#8221; and &#8220;file2.txt&#8221; and displays them.<\/li>\n<\/ul>\n\n\n\n<p>The <code>cat<\/code> command is commonly used to view the contents of text files or to combine files when necessary.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"less-view-file-content-page-by-page\">less (View File Content Page by Page)<\/h3>\n\n\n\n<p>The <code>less<\/code> command is used to view the contents of a file in a paginated manner. It allows you to scroll through the file and search for specific text. The <code>less<\/code> command is particularly useful for viewing large files without overwhelming the terminal with a long scroll. To use it, simply type <code>less<\/code> followed by the file name. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>less myfile.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>less myfile.txt<\/code> opens the file &#8220;myfile.txt&#8221; in the &#8220;less&#8221; viewer.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"grep-search-for-text-in-files\">grep (Search for Text in Files)<\/h3>\n\n\n\n<p>The <code>grep<\/code> command is used to search for specific text patterns within files. It allows you to find lines that match a given pattern and display them on the terminal. The <code>grep<\/code> command is not only useful for searching for specific text patterns within files but also supports powerful regular expressions. Regular expressions allow for more complex and flexible pattern matching. You can use them to search for patterns that match specific criteria, such as email addresses, phone numbers, or log entries with specific formats.\u00a0Here&#8217;s an example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>grep \"keyword\" file.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>grep \"keyword\" file.txt<\/code> searches for the word &#8220;keyword&#8221; within &#8220;file.txt&#8221; and displays the matching lines.<\/li>\n<\/ul>\n\n\n\n<p>The <code>grep<\/code> command supports various options and regular expressions, making it a powerful tool for text searching and filtering.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"find-search-for-files-and-directories\">find (Search for Files and Directories)<\/h3>\n\n\n\n<p>The <code>find<\/code> command helps you search for files and directories based on various criteria, such as name, size, type, permissions, and modified time. It allows you to locate files and perform operations on them. Here are a few examples of using the <code>find<\/code> command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>find \/path\/to\/search -name myfile.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>find \/path\/to\/search -name myfile.txt<\/code> searches for a file named &#8220;myfile.txt&#8221; within the specified directory and its subdirectories.<br><\/li>\n\n\n\n<li><code>find \/path\/to\/search -type d<\/code> lists all directories within the specified directory.<\/li>\n<\/ul>\n\n\n\n<p>The <code>find<\/code> command is a powerful tool for locating and managing files based on specific conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"chmod-change-file-permissions\">chmod (Change File Permissions)<\/h3>\n\n\n\n<p>The <code>chmod<\/code> command is used to change the permissions of files and folders. In Linux, file permissions control who can read, write, or execute a file. The <code>chmod<\/code> command takes a numeric mode or a symbolic representation to modify permissions. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>chmod +x script.sh<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>chmod +x script.sh<\/code> grants execute permission to the file &#8220;script.sh.&#8221;<br><\/li>\n\n\n\n<li><code>chmod 644 file.txt<\/code> sets read and write permissions for the file owner and read-only permissions for group members and others.<\/li>\n<\/ul>\n\n\n\n<p>Understanding and managing file permissions is crucial for ensuring the security and integrity of your system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"chown-change-file-ownership\">chown (Change File Ownership)<\/h3>\n\n\n\n<p>The <code>chown<\/code> command allows you to change the ownership of files and folders. Ownership refers to the user and group that has control over a file or directory. By using the <code>chown<\/code> command, you can transfer ownership to a different user or group. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>chown john:staff file.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>chown john:staff file.txt<\/code> changes the ownership of &#8220;file.txt&#8221; to the user &#8220;john&#8221; and the group &#8220;staff.&#8221;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"tar-archive-and-extract-files\">tar (Archive and Extract Files)<\/h3>\n\n\n\n<p>The <code>tar<\/code> command is used to create archives and extract files from them. It is often used in conjunction with compression utilities, such as gzip or bzip2, to create compressed archives. Here are a few examples of using the <code>tar<\/code> command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>tar -cvf archive.tar file1.txt file2.txt<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>tar -cvf archive.tar file1.txt file2.txt<\/code> creates a tar archive containing &#8220;file1.txt&#8221; and &#8220;file2.txt.&#8221;<br><\/li>\n\n\n\n<li><code>tar -xvf archive.tar<\/code> extracts the files from the &#8220;archive.tar&#8221; archive.<\/li>\n<\/ul>\n\n\n\n<p>The <code>tar<\/code> command offers a flexible and efficient way to manage and transfer collections of files.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"gzip-compress-files\">gzip (Compress Files)<\/h3>\n\n\n\n<p>When it comes to file compression, the <code>gzip<\/code> command is widely used. It reduces the size of files and is often combined with the &#8220;tar&#8221; command.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>gzip file.txt<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ping-check-network-connectivity\">ping (Check Network Connectivity)<\/h3>\n\n\n\n<p>The <code>ping<\/code> command is used to check network connectivity between your system and a remote host. It sends ICMP (Internet Control Message Protocol) echo request packets to the specified host and waits for an ICMP echo reply. This helps you determine if a remote host is reachable and measure the round-trip time. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ping google.com<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>ping google.com<\/code> sends ICMP echo requests to the Google server and displays the round-trip time for each reply.<\/li>\n<\/ul>\n\n\n\n<p>The <code>ping<\/code> command is a valuable utility for network troubleshooting and diagnosing network connectivity problems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"wget-download-files-from-the-web\">wget (Download Files from the Web)<\/h3>\n\n\n\n<p>The <code>wget<\/code> command is commonly used to download files from the web. It supports downloading files via HTTP, HTTPS, and FTP protocols. To use the <code>wget<\/code> command, specify the URL of the file you want to download. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>wget https:\/\/example.com\/file.zip<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>wget https:\/\/example.com\/file.zip<\/code> downloads a file named &#8220;file.zip&#8221; from the specified URL.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"ssh-secure-shell\">ssh (Secure Shell)<\/h3>\n\n\n\n<p>The <code>ssh<\/code> command allows you to establish secure remote shell connections to remote servers or systems. It provides a secure encrypted communication channel for executing commands or managing remote systems. To connect to a remote server, use the following syntax: <code>ssh username@hostname<\/code>. For example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>ssh john@example.com<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>ssh john@example.com<\/code> establishes an SSH connection to the server &#8220;example.com&#8221; with the username &#8220;john.&#8221;<\/li>\n<\/ul>\n\n\n\n<p>The <code>ssh<\/code> command is widely used for remote administration, file transfers, and secure communication between systems.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"top-monitor-system-processes\">top (Monitor System Processes)<\/h3>\n\n\n\n<p>The <code>top<\/code> command provides real-time monitoring of system processes.
