![]() ![]() For example, the below command creates a new file if it doesn’t exist already. We can use the combination of the cat command and redirection operator to create a file. $ echo "Append data using the tee command" | tee -a tecmint.txt To append the contents to the existing file, use the -a option of the tee command, which allows us to append the data at the end of the existing file. In this example, we can observe that the tee command overwrites the contents of the tecmint.txt file which was created and updated in earlier examples. If you want to overwrite the content of a file using the tee command, you can use the following command: $ echo "Overwrite file using the tee command" | tee tecmint.txt Now type or paste the content you want to write to the file and then press Enter and hit Ctrl + C close the input window as shown. The tee command writes the output of the command to the standard output stream as well as the file.įor example, to create a file named “ tecmint.txt“, use the tee command, which will be ready to accept input. Similar to the redirection operator we can also use the tee command to create a file. Instead, it just updates the time stamp ( access time and modification time) of the existing file. ![]() One more way of creating a file is using the touch command, which offers the safest way of creating an empty file because it never overwrites the existing file. It is worth noting that, just like the redirection operator, the append operator will also create an empty file if it doesn’t exist already. In the above output, we can see that the new line gets appended at the end of the file. In such a case, we can use the > redirection operator, which is used to append the contents to the existing file. However, we can redirect the output of the other Linux commands as well to create a file.Īlso, it is important to note that the > redirection operator is used to overwrite the contents of an already existing file, which cause data loss if the operation is performed carelessly. It is important to note that in this example, we have used the echo command to create a file. ![]() $ echo " is a popular Linux blog" > tecmint.txtĬreate a File and Write Content to the File In such cases, you can use the output redirection operator (>) to create a file and write content to it using the echo command as shown. Sometimes, we want to create a non-empty file quickly. Create File and Write Content Using > Redirection Operator In the above example, we can see that the head command is not showing any output as the file is empty. Hence one should be very careful while using the redirect operator. However, it makes the file empty if it exists already. The same (>) operator is also used to create a file if it doesn’t exist already. In Linux, the redirection operator (>) is used to redirect the output of a command to a file instead of displaying it on the terminal. Create an Empty File Using > Redirection Operator In this easy-to-follow guide, we will discuss various ways of creating a file in Linux. However, the same can be achieved using the command line interface as well. For example, the /etc/hosts file stores static table lookup for hostnames, the /etc/crontab file contains instructions for the cron daemon, and so on.Ĭertainly, we can use graphical tools to create files. Linux uses plain text files to store important configurations. Files provide a reliable way of storing data in a persistent manner. Files are one of the most important objects of any operating system and Linux is not an exception.
