เป็นคำสั่งที่ใช้ในการสร้างหรือแก้ไข file ข้อมูล text เป็นประเภทเดียวกับ editor พื่นฐาน ที่ติดตั้งมาการติดตั้ง Unix หรือ Linux



 Places the cursor on line number line and at column number column (at least one of which must be specified) on startup, instead of the default line 1, column 1.

 -A, --smarthome
 Make the Home key smarter. When Home is pressed anywhere but at the very beginning of non-whitespace characters on a line, the cursor will jump to that beginning (either
 forwards or backwards). If the cursor is already at that position, it will jump to the true beginning of the line.

 -B, --backup
 When saving a file, back up the previous version of it, using the current filename suffixed with a tilde (~).

 -C directory, --backupdir=directory
 Make and keep not just one backup file, but make and keep a uniquely numbered one every time a file is saved -- when backups are enabled. The uniquely numbered files are
 stored in the specified directory.

 -D, --boldtext
 Use bold text instead of reverse video text.

 -E, --tabstospaces
 Convert typed tabs to spaces.

 -F, --multibuffer
 Enable multiple file buffers (if support for them has been compiled in).

 -G, --locking
 Enable vim-style file locking when editing files.

 -H, --historylog
 Log search and replace strings to ~/.nano/search_history, so they can be retrieved in later sessions.

 -I, --ignorercfiles
 Don't look at the system's nanorc nor at ~/.nanorc.

 -K, --rebindkeypad
 Interpret the numeric keypad keys so that they all work properly. You should only need to use this option if they don't, as mouse support won't work properly with this
 option enabled.

 -L, --nonewlines
 Don't add newlines to the ends of files.

 -N, --noconvert
 Disable automatic conversion of files from DOS/Mac format.

 -O, --morespace
 Use the blank line below the titlebar as extra editing space.

 -P, --positionlog
 For the 200 most recent files, log the last position of the cursor, and place it at that position again upon reopening such a file. (The old form of this option, --poslog,
 is deprecated.)

 -Q "characters", --quotestr="characters"
 Set the quoting string for justifying. The default is "^([ \t]*[#:>\|}])+" if extended regular expression support is available, or "> " otherwise. Note that \t stands for
 a Tab.

 -R, --restricted
 Restricted mode: don't read or write to any file not specified on the command line; don't read any nanorc files nor history files; don't allow suspending nor spell checking;
 don't allow a file to be appended to, prepended to, or saved under a different name if it already has one; and don't use backup files. This restricted mode is also accessi‐
 ble by invoking nano with any name beginning with 'r' (e.g. "rnano").

 -S, --smooth
 Enable smooth scrolling. Text will scroll line-by-line, instead of the usual chunk-by-chunk behavior.

 -T number, --tabsize=number
 Set the size (width) of a tab to number columns. The value of number must be greater than 0. The default value is 8.

 -U, --quickblank
 Do quick statusbar blanking. Statusbar messages will disappear after 1 keystroke instead of 25. Note that -c overrides this.

 -V, --version
 Show the current version number and exit.

 -W, --wordbounds
 Detect word boundaries more accurately by treating punctuation characters as part of a word.

 -Y name, --syntax=name
 Specify the name of the syntax highlighting to use from among the ones defined in the nanorc files.

 -c, --constantshow
 Constantly show the cursor position. Note that this overrides -U.

 -d, --rebinddelete
 Interpret the Delete key differently so that both Backspace and Delete work properly. You should only need to use this option if Backspace acts like Delete on your system.

 -h, --help
 Show a summary of the available command-line options and exit.

 -i, --autoindent
 Indent new lines to the previous line's indentation. Useful when editing source code.

 -k, --cut
 Make the 'Cut Text' command (normally ^K) cut from the current cursor position to the end of the line, instead of cutting the entire line.

 -m, --mouse
 Enable mouse support, if available for your system. When enabled, mouse clicks can be used to place the cursor, set the mark (with a double click), and execute shortcuts.
 The mouse will work in the X Window System, and on the console when gpm is running. Text can still be selected through dragging by holding down the Shift key.

 -n, --noread
 Treat any name given on the command line as a new file. This allows nano to write to named pipes: it will start with a blank buffer, and will write to the pipe when the
 user saves the "file". This way nano can be used as an editor in combination with for instance gpg without having to write sensitive data to disk first.

 -o directory, --operatingdir=directory
 Set the operating directory. This makes nano set up something similar to a chroot.

 -p, --preserve
 Preserve the XON and XOFF sequences (^Q and ^S) so they will be caught by the terminal.

 -q, --quiet
 Do not report errors in the nanorc files nor ask them to be acknowledged by pressing Enter at startup.

 -r number, --fill=number
 Hard-wrap lines at column number. If this value is 0 or less, wrapping will occur at the width of the screen less number columns, allowing the wrap point to vary along with
 the width of the screen if the screen is resized. The default value is -8. This option conflicts with -w -- the last one given takes effect.

 -s program, --speller=program
 Use this alternative spell checker command.

 -t, --tempfile
 Always save a changed buffer without prompting. Same as Pico's -t option.

 -u, --unix
 Save a file by default in Unix format. This overrides nano's default behavior of saving a file in the format that it had. (This option has no effect when you also use

 -v, --view
 View-file (read-only) mode.

 -w, --nowrap
 Disable the hard-wrapping of long lines. This option conflicts with -r -- the last one given takes effect.

 -x, --nohelp
 Don't show the two help lines at the bottom of the screen.

 -z, --suspend
 Enable the suspend ability.

 -$, --softwrap
 Enable 'soft wrapping'. This will make nano attempt to display the entire contents of any line, even if it is longer than the screen width, by continuing it over multiple
 screen lines. Since '$' normally refers to a variable in the Unix shell, you should specify this option last when using other options (e.g. 'nano -wS$') or pass it sepa‐
 rately (e.g. 'nano -wS -$').

 -a, -b, -e, -f, -g, -j
 Ignored, for compatibility with Pico.
