Apart from various other use-cases, the cat command in Linux can also be used for viewing the contents of a file very effectively. There are different ways in which you can use this command for serving this purpose. Therefore, in this tutorial, we will be sharing with you some of the ways in which you can use the cat command for displaying the contents of a file in Linux Mint 20.3.
Using the Cat Command for listing the Contents of a File in Linux Mint 20.3:
For learning how you can use the cat command in Linux Mint 20.3 for listing the contents of a file, you can go through the following three examples. We will be using two different files for demonstration in these examples i.e. sample.txt and test.txt. You can learn to create a file with the cat command by visiting the link that follows: https://linuxways.net/centos/how-to-create-a-file-in-linux-using-cat-command/.
Example # 1: Listing the Contents of a Single File with the Cat Command:
You can list the contents of a single file with the help of the cat command by running it in the manner shown below:
$ cat sample.txt
Here, “sample.txt” is the name of the text file whose contents we want to list down.
The contents of our specified file are shown in the following image:
Example # 2: Using Multiple Cat Commands at Once:
At times, you might want to run multiple cat commands at once for listing the contents of more than one file at a time. You can do that in the manner shown below:
$ cat sample.txt; cat test.txt
Here, “sample.txt” and “test.txt” are the two text files whose contents we want to list down. In the same manner, you can also list down the contents of more than two files by using multiple cat commands with the file names while separating them with the help of semi-colons.
The contents of our specified files are shown in the following image:
Example # 3: Listing the Contents of Multiple Files with a Single Cat Command:
A better way of listing down the contents of multiple files at once is by using a single cat command. This process will not only be more efficient but will also be computationally less expensive. You can do this by running the cat command in the manner shown below:
$ cat sample.txt test.txt
Here, we have used the same text files that we had used in our second example. However, this time, instead of using multiple cat commands while separating them with semi-colons, we have used a single cat command followed by the names of all the files whose contents are to be displayed. The names of these files have been separated simply by using spaces.
The contents of our specified files are shown in the image that follows:
By taking help from the different examples that have been shared in this tutorial, you can easily use the cat command for listing the contents of a file in Linux Mint 20.3.
