Form command in Linux is made use of to set up the document in a precise purchase according to the choice made use of. It will help in sorting the information in the file line by line. Sort command has diverse capabilities that it follows in the resultant of commands. 1st is that the strains getting figures will appear prior to the alphabetic strains. These traces obtaining reduced scenario letters will be shown before than the traces acquiring the exact character in uppercase.


You need to have to put in Ubuntu on a virtual box and configure it. End users have to be established to have the privileges of accessing the purposes.



This is a uncomplicated illustration of sorting a file obtaining information of names. These names are not in purchase, and to make them in an buy kind you want to type them.

So, take into consideration a file named file1.txt. We will exhibit the contents in the file by applying the appended command:

Now use the command to kind the text in the file:

Preserve the Output in A further File

By working with the kind command, you will appear to know that its final result is only exhibited but not saved. To seize the final result we need to have to shop it. For this objective –o choice in the sort command is made use of.

Take into consideration an instance title sample1.txt acquiring the names of vehicles. We want to type them and conserve the resultant facts in a individual file. A file named end result.txt is designed at operate-time and the respective output is stored in it. The data of sample1.txt is transferred to the resultant file and then with the assist of –o the respective information is sorted. We have exhibited the facts working with the cat command:

$ kind sample1.txt > result.txt

$ kind –o final result.txt sample1.txt

$ Cat result.txt

The output exhibits that the data is sorted and saved in yet another file.

Sort for Column Amount

Sorting is not only finished on a one column. We can form one column simply because of the next column. Permit us have an example of a textual content file in which there are names and marks of the learners. We want to arrange them in ascending buy. So we will use the search phrase –k in the command. Whilst –n is utilized for numerical sorting.

As there are two columns, so 2 is utilised with n.

Look at the Sorted Situation of a File

If you are not confident if the existing file is sorted or not, take away this doubt employing the command that clarifies the confusion and displays the information. We will arrive by two essential examples:

Unsorted Knowledge

Now, think about an unsorted file obtaining the vegetable names.

The command will use the search term –c. This will test regardless of whether the facts in the file is sorted or not. If the facts is unsorted, then the output will show the line range of the to start with word where unsortedness is present in the file and also the phrase.

From the specified output, you can recognize that the 3rd phrase in the file was misplaced.

Sorted Details

In this scenario, when the info is already structured, there is no need to do just about anything else. Look at a file outcome.txt.

From the end result, you can see that no concept is demonstrated which indicates that the information in the respective file is presently sorted.

Eliminate Duplicate Items

Right here is the most beneficial solution of some sort. This helps in taking away the recurring words and phrases in a file and make the file merchandise organized much too. It also maintains the consistency of the information in the file.

Look at the file title file2.txt getting the names of topics but one matter is repeated a number of situations. Form command will then use the –u search term to clear away duplication and relatedness:

Now, you can see that the repeated products are eliminated from the output and that the info is also sorted.

Form Making use of Pipe in a Command

If we want to sort the information of the file by furnishing the record of the directory regarding the file measurements, we will enlist all respective knowledge of the directory. The ‘ls’ is made use of in command and -l will exhibit it. The Pipe will support in displaying the information in an structured method.

$ ls –l /house/aqsayasin/ | sort –nk5

Random Sorting

In some cases, though doing any function, you can mess with the arrangement. If you want to arrange the information in any sequence and if there are no requirements for sorting, then random sorting is preferred. Look at a file named sample3.txt owning the names of the continents.

The respective output reveals that the file is sorted and things are organized in a various order.

Form the Information of A number of Information

One particular of the most valuable commands of sorting is to type the data of different data files at a time. This can be done by working with the uncover command. The output of the uncover command will act as an input for the command immediately after the pipe that is a kind command. Locate key phrase is applied to give only one file on just about every line, or we can say that it takes advantage of a break following each word.

For instance, let us contemplate three information named sample1.txt, sample2.txt, and sample3.txt. Here the “?” signifies any number that is adopted by the phrase “sample”. Obtain will fetch all a few documents and their data will be sorted with the assistance of a kind command with the pipe initiative:

$ discover –name “sample?.txt” –print0 | sort –files0-from=-

The output shows that the knowledge of all sample.txt sequence documents are exhibited and is organized and structured alphabetically.

Sort with Be part of

Now, we are introducing an case in point that is quite distinctive from the kinds that are discussed earlier in this tutorial. In addition to type, we have used be a part of. This course of action is finished in these a way that both of those the data files are very first sorted and then joined employing a be a part of search phrase.

Take into account two files you want to be part of.

Now use the beneath-cited question to apply the presented thought:

$ sign up for <(sort sample2.txt) <(sort sample3.txt)

You can see from the output that the data both files are combined in sorted form.

Compare Files Using Sort

We can also adopt the concept of comparing two files. The technique is the same as it was for joining. Firstly two files are sorted and then the data in them are compared.

Consider the same two files as discussed in the previous example. Sample2.txt and sample3.txt:

$ comm <(sort sample2.txt) <(sort sample3.txt)

The data is sorted and arranged alternatively. The initial line of the file sample2.txt is written next to the first line of the file sample3.txt.


In this article, we have talked about the basic functionality and options of the sort command. Linux sort command is very beneficial in the maintenance of data and filtering all useless items from the files.
