Debian Text Editors

Debian provides several text editors with different learning curves and capabilities.

Beginner-friendly, simple modal editor. Starts in edit mode:

nano file.txt

Common commands (Ctrl prefix):

• Ctrl+X — exit
• Ctrl+O — save
• Ctrl+W — search
• Ctrl+U — undo
• Ctrl+V — next page

Quick, non-destructive, forgiving. Good for quick edits and scripts.

Powerful but steep learning curve. Three modes:

• Normal (default) — navigation and commands
• Insert (press i) — edit text
• Command (:) — file/search commands

Basic workflow:

vim file.txt
i              # enter insert mode
[edit text]
Esc            # back to normal
:wq            # save and quit
:q!            # quit without saving

Useful normal mode commands:

• dd — delete line
• yy — copy line
• p — paste
• /pattern — search
• :%s/old/new/g — replace all

Vim has syntax highlighting, text objects, macros, and extensive customization.

Extensible, powerful, but also steep. Heavy Ctrl usage. Start:

emacs file.txt

Commands:

• Ctrl+X Ctrl+C — exit
• Ctrl+X Ctrl+S — save
• Ctrl+S — search
• Ctrl+_ — undo

Less common on systems without X11; vim is usually available everywhere.

Minimal line editor, rarely needed:

ed file.txt

Useful only when nothing else available (embedded systems, minimal recovery).

Set default editor:

export EDITOR=vim
export EDITOR=nano

Used by crontab -e, visudo, and many tools. Pick one and learn it:

• Quick edits → nano
• Programming → vim
• Extensive config → emacs

For shell scripts: vim with syntax highlighting makes debugging easier. For one-liners: nano is faster.
