How to Append Text to End of File in Linux?
  • Last Updated : 07 Mar, 2021

On Linux, while working with files in a terminal sometimes we need to append the same data of a command output or file content. Append means simply add the data to the file without erasing existing data. Today we are going to see how can we append the text in the file on the terminal.

The >> operator redirects output to a file. If the mentioned file doesn’t exist the file is created and then the text is appended to the file.

echo "Which is the best Linux Distro?"  >>  file.txt
