How to add text to a file in Linux via the command line (In 3 Steps)
From the point of view of the Linux operating system, all files are just sequences of bytes; Linux makes no distinction between files that contain human-readable text, hard-coded database tables, or executable machine code. The Linux command line, also called a “shell”, has powerful mechanisms for adding content to a file. In particular, you can add additional text to a Linux file from the command line.

Step 1
Log into the computer.

Step 2
Launch a shell, by logging in in text mode or by launching a Terminal window from the graphical desktop.

Step 3
Enter the following command in the shell:
echo “new text” >> /home/fangulo/TextFile.txt
Replace “new text” with the text you want to add to the file, and replace “/home/fangulo/TextFile.txt” with the name and full path of the file to which you want to add the text. Press “Enter”. When the shell asks you for a new command, the text will have been added to the file.
