You can append text to the end of a file in Linux using the echo command and the >> operator. The echo command outputs the specified text, and the >> operator appends the output to the end of the specified file.
Here’s an example of how to append text to the end of a file named file.txt:
echo "This is the text that will be appended." >> file.txt
In this example, the text "This is the text that will be appended." will be appended to the end of the file file.txt. If the file file.txt does not exist, it will be created.
You can also append text to the end of a file using the tee command and the -a option. The tee command outputs the specified text to both the console and a file. The -a option tells tee to append the output to the end of the file, rather than overwriting the file.
Here’s an example of how to append text to the end of a file named file.txt using the tee command:
echo "This is the text that will be appended." | tee -a file.txt
This example works similarly to the previous one, but it uses the tee command instead of the echo command and >> operator.
