The sensible-editor command is a Linux command that opens the default editor set in the system. It is a part of the Debian/Ubuntu Linux distribution and is used to open the default text editor for the user.
When you run the sensible-editor command, it will automatically open the default text editor set in the system. This editor can be different for different users or systems. For example, on Ubuntu, the default text editor is set to nano while on Debian, it is set to vim.
The sensible-editor command is often used in scripts or configuration files where a text editor is needed. Instead of hardcoding the name of the editor, the sensible-editor command can be used to open the default editor, regardless of what it is.
For example, if you have a script that needs to open a configuration file for editing, you can use the sensible-editor command to open the file in the default editor:
# sensible-editor /path/to/config/file.conf
This will open the file /path/to/config/file.conf in the default editor set in the system.
You can also set the default editor by setting the VISUAL or EDITOR environment variable. For example, if you want to set the default editor to nano, you can add the following line to your .bashrc file:
# export VISUAL=nano
Then, running sensible-editor will open the nano editor.
