This wikiHow teaches you how to save different types of files from the Linux command line. If you're using an app that has a graphical user interface (GUI), saving files is easy—you'll usually just need to click the File menu and select Save . Read on to learn how to save files in command line text editors, how to save the output of a command, and how to save an existing file to a new file.

- Press Enter to save the file.
- Type :q and press Enter to quit Vi or Vim and return to the command line.
Steps

Type :w filename and press ↵ Enter . You can skip entering the file name if you're editing an existing file and want to save your changes to that same file.
- For example, if you're editing a file that already has a file name and want to save the changes you've made, type :w and press Enter . But if you're editing a brand new file and want to call it wikiHow , you'd use :w wikiHow instead.

- For example, if you want to list the contents of the current directory and save the output to a new file, you could type ls -a now.
-
Type a space and then > . Using the prior example, your command would now look like this: ls -a > .
- If you want to append the output to an existing file, use >> instead of > .
-
Type a space and enter the name of the file you want to create. If you wanted to save the results to a file called filelist , the command would look like ls -a > filelist .
- If you're appending the output to an existing file, you'd use ls -a >> filename .
-
Press ↵ Enter to run the command. This creates a file in the current directory called filelist that contains the output of the ls -a command.
