How to save terminal command line output to a file

Normally, when you run a command in the terminal, the command output is printed directly to the terminal and displayed. You can also run it in a bash-based terminal if you want to save the output to an external text file. Example: Ubuntu. Redirect the output and save it to a text file. Useful for viewing the output later. This article will show you all the available methods to output terminal output to a file.

command > /path/to/file.txt
