<p>Ubuntu can be considered as Linux based distribution system which is open source and entirely free in the common market. This is the most commonly used Linux flavor in the industry. </p>

<p>There are numerous commands that allow us to <strong>handle files/directories </strong>and deal with users. </p>

<p>Let us start with commands related to handling files and directories:- </p>

<p>PWD stands for PRESENT WORKING DIRECTORY. This command is mainly used for displaying the specific directory where the command executer is currently belonged to. </p>

<p>Sometimes in the case of the Ubuntu Linux platform, users are unable to understand in which directory he is right now. Then <strong>PWD </strong>is the key command for understanding the same. </p>

<p>Now, as we have an idea of the present working directory, now we wish to switch the directory – For this Ubuntu has provided us with the below command… </p>

<p>CD stands for “<strong>Changing Directory </strong>”, and as per the naming convention, it helps us to change from the current working directory to the specified path. </p>

<p>It helps us to create an empty file in the present directory. </p>

<p>It helps us to display the content of the file without opening the file. </p>

<p>The echo command in Linux simply displays a line of text/string which is passed in as an argument. It is commonly used for debugging shell programs inside the terminal. </p>

<p>If the string is containing the <strong>newline (\n) </strong>in it, then we can this command to show. </p>

<p>The ‘<strong>-e </strong>‘ tag enables the echo command to recognize the backslash escape sequences inside the argument. </p>

<p>The rm command in Linux helps you delete files and directories. To be more specific, rm deletes all references to objects from the filesystem. </p>

<p>We can also use tags with this command. For example, if you want to request confirmation from the developer before deleting the corresponding file, then use the below command. </p>

<p>The <em>cp </em>command in Linux translates to ‘copy’. It is used to copy files/directories from one location to another from inside the terminal. </p>

<p>Let us assume we have two separate files ‘<em>First.txt </em>‘ and ‘<em>Second.txt </em>‘ inside our current working directory. Their contents are as follows: </p>

<p>Now, if we use this command<strong><span>cp First.txt Second.txt </span> </strong>will give the result as: </p>

<p>And here you go…now you will be able to see that the text from the First.txt file is being copied to Second.txt. </p>

<p>So, that’s all about the basic commands of Ubuntu, these are the most frequently used commands which every developer should know. We will also discuss the advanced commands of document handling in Linux based operating system. So stay connected with our latest posts. </p>

<p>Hope you like it👍 and if you find this useful then don’t forget to share this with your friends or on social media.
