Mess up the wrong system file, and you can find yourself locked out of your computer following a reboot. Warning: Don’t edit system files if you don’t know exactly what your changes are going to do to your system. To be strictly accurate you’ll be able to open a system file even if you don’t use sudo, but you won’t be able to save any changes back to the file unless you have used sudo. To edit a system file, you will usually need to use sudo because the owner of the file is likely to be root. Click the green “Save” button to save the file. You can browse to the directory you wish to save the file in, and you can provide a name for the file. This will open a standard file save dialog. To save your file with a different name or in a different location click the menu button on the toolbar and then select “Save As” from the menu. You can also press Ctrl+S to save the file. To save your changes, click the “Save” button in the toolbar. It acts as a reminder that if you want to keep the changes you need to save the file. This lets you know that changes have been made to the content of the file. If you wish to open a different file, click the “Other documents…” button at the bottom of the menu. If you want to re-open one of the listed files click on the name of the file. You can also press Ctrl+O to open a file. To open an existing text file click the “Open” button in the gedit toolbar. Type gedit, a space, an ampersand &, then press Enter-like this: gedit & You get the command line prompt back straight away and you can carry on using the terminal window even when gedit is running. If you want to use the terminal window while gedit is still open, launch gedit with this command instead.
The terminal window will wait for gedit to close before it returns you to the command prompt. It’s often named “Text Editor.” Just search the applications menu for “gedit.” Of course, you can also launch gedit from your Linux desktop’s application menu. You can get on with the task of typing up whatever you’re working on with no distractions.
It’s an uncluttered and clean application window.
