Nano Editor Settings
1. Smooth Scrolling
nano supports two types of scrolling. One is chunk-by-chunk, which scrolls multiple lines, and the other is line-by-line. By default, nano scrolls in multiple lines. To scroll line by line or softly (that is, scroll up or down by just pressing the arrow keys), add the following line to the settings:
Or use the following switch when running nano:
-S or --smooth
2- Auto Indentation
This option is also very useful for programmers. The logic is that it calculates the indentation based on the distances of the previous line. Add this line in the settings file:
Or use the following switch at runtime:
-i or --autoindent
Be sure to enable this feature. Extremely useful.
Imagine you manipulated a system configuration file and now there is a problem with the system and you do not remember what you changed. With this option, every time you manipulate a file, nano will keep a copy of the unmodified version.
Add the following line in the settings file:
Or use the following switch at runtime:
-B or --backup
By default, backups are stored next to the original file, but one of the great things about nano is that you can ask it to keep all the backups in a specific path.
In the configuration file, add the following line and enter your desired address:
set backupdir "/home/user/nano-backups"
4- Nano history
If you need to access the search / replace history in nano, just add the following line to the configuration file. The history of all searches is stored in the ~/.nano-history file.
You can also use the following switch to save history:
-H or --historylog
5- Activate the mouse
Although using a mouse with these types of editors will only slow down, it may be useful for actions such as copying or cutting.
Here are the runtime options:
-m or --mouse
For a complete list of available options, get help from nano help:
nano --help or man nano
