As Linux users, we all have to change to the Terminal at 1 place or yet another to carry out some procedure jobs, no matter if they might have to do with installing new plans or removing old ones. For individuals that are fond of utilizing the command-line, slash operators will be very acquainted. But individuals who are not have arrive to the ideal place as we will be talking about this function in wonderful depth in this article.

A limited breakdown

Ahead of we get into what dot backslash usually means in Linux, permit us determine some discussion factors. All of these are critical to being familiar with the dot slash element, and we have taken it on ourselves to stroll you by all of it.

So, with no any further ado, let us get into it.

What is Route?

In Linux and other Unix-like devices, we use the command-line to run executable packages by means of instructions. On the other hand, the shell does want to be pointed in the proper direction by a little something to handle our demands of functioning executables. That is in which the environmental variable Path comes in.

Path is an environmental variable liable for telling the shell in which to glance for the programs (executable documents) we want to run. This variable retains excellent significance in the operating procedure because it effectively boosts the convenience and security of the method.

Environmental variables are just a specific class of variables that maintain modifiable values. Hold in head that there is a subtle but critical distinction concerning the uppercase Path and the lowercase route. The 2nd one is simply the handle of a listing or file in the system.

You can look at the Path variable by jogging the pursuing command in the Terminal.

Now that we have lined some floor about the environmental variable Path, we understand about the root listing to use these concepts in conjunction with our principal subject matter.

What is the root listing?

This portion will extend on the root listing devoid of having totally shed in the details of the Filesystem Hierarchy Normal (FHS) of Linux. It is closely linked to the Route variable we earlier pointed out thus, a modest dialogue is needed.

The root directory sits comfortably at the really major of the Linux filesystem hierarchy. It has each individual file and directory on your personal computer, which include the libraries, boot documents, binaries, consumer data files, configuration settings, non permanent files, and considerably a lot more.

In small, the root directory serves as the general reference position for addressing documents and directories in your personal computer.

Big difference among complete and relative route

Next on our checklist is the absolute and relative route. We will be utilizing the principles mentioned previously mentioned of root and path to establish the variation between the two.

An absolute path is a file or listing spot about the root listing, not the existing directory. Thus, the full address of a file in the computer is referenced by the root directory. The complete route incorporates all the necessary information and facts about the file or directory it is describing.

On the other hand, a relative path is used to describe a file/listing spot regarding the current directory. It does not trace the address of a file from the root directory, alternatively from exactly where you have established the latest listing.

What does dot imply in Linux?

Dot, or “.” addresses the current user listing. As a result of this characteristic or operator, you can find in which the current directory is set. Let’s see how we can obtain that as perfectly.

Open up a new Terminal window through the Things to do menu or hit Ctrl + Alt + T on your keyboard. The subsequent stage is to execute the command supplied underneath.

You can see that in the output, the current person directory is highlighted by the line ending with a dot.

With that getting mentioned, we are midway as a result of comprehending the function of dot backslash in Linux. Allow us move on to the up coming area to go over two sorts of slash operators (ahead and again).

What does slash imply in Linux?

As pointed out earlier, there are two sorts of slashes, both with entirely different applications. For that reason, we ought to draw a obvious difference concerning the two.

The ahead slash, /, when appended to the conclusion of a dot, tends to make positive that you are not working on a file. The similar happens when incorporating a slash to the conclusion of the name of a directory. Let us choose a appear at how you can use it with a dot.

To start with, we check out our property listing by the subsequent command.

We are going to spot a sample textual content file in the folder /dwelling/sample/. We can use dot slash to do this devoid of modifying the latest listing.

$ nano ./sample/sample.txt

Notice that our sample text file was accessed and modified without us obtaining to transform the latest directory. Future, we can check out the changes we created as a result of the cat command.

$ cat ./sample/sample.txt

And now, we get the output as:

To conclude the tale of “./”, we can say that it makes it possible for us to address the present-day directory. So, we can also use it on our Path variable to obtain information that are not in our current listing devoid of ever leaving the existing directory.

Up coming, we have the backslash, . In Unix methods, and even some programming languages like C, the job of the backslash is to indicate to the process that the following character has a exclusive that means. Therefore, it performs as an escape character. For instance, a lowercase n, when applied with a backslash, n, signifies a new line character. Several other characters can be employed instead of n to achieve different jobs. Let’s put into practice this in our Terminal. In this article, %s is the string placeholder, n is the newline character, and the rest of the three strains are the strings inputted to the placeholders.

$ printf ‘%sn%sn%sn ‘I stay because’ ‘The mountains do not laugh’ ‘And the worms do not sing.’

So, now we have shown the objective of both equally of the slashes.


In this write-up, we went into wonderful element about the dot backslash function in Linux. We discovered the basic concepts of Route, relative and absolute paths, the root directory, dots, slashes, and eventually, how they are applied in conjunction with just about every other.
